Definition

MENA, short for Middle East and North Africa, is an informal regional grouping stretching from Morocco to Iran and south to Sudan, with no official member list.

Key takeaways

  • Depending on who draws the map, MENA covers between 19 and 27 countries, with Turkey a classic borderline case.
  • The region holds more than half of the world's proven oil reserves and about 40% of its natural gas reserves.
  • Saudi Arabia is the largest MENA economy, with 2025 GDP of $1.28 trillion, followed by Israel at $610.78 billion.
  • The GCC is a formal union of six Gulf states, all inside MENA, while MENA itself is a label analysts assign.

MENA stands for Middle East and North Africa, a regional grouping that runs roughly from Morocco on the Atlantic coast of northwest Africa to Iran in southwest Asia, and south to Sudan. It is a convention, not a treaty bloc or a legal entity. No official member list exists, so the region covers between 19 and 27 countries depending on who draws the map. International institutions, economists, investors and multinational companies use the label because the area shares a heavy concentration of oil and natural gas resources and overlapping political and trade ties.

What MENA means

The term joins two geographic labels that are themselves loosely defined:

  • Middle East usually refers to countries on or near the Arabian Peninsula and the eastern Mediterranean, plus Iran. Broad definitions also take in Turkey, and sometimes the South Caucasus states of Armenia and Azerbaijan. Afghanistan and Pakistan are occasionally grouped with the Middle East but are not normally counted in MENA.
  • North Africa usually means Algeria, Egypt, Libya, Morocco, Tunisia, Sudan and Western Sahara. Some definitions stretch east to include Djibouti and Somalia.

Combining the two produces a region whose edges move with the purpose of the analysis. A development lender building a regional dataset, a fund manager defining a benchmark, and a company organizing its sales territories may each use a different list.

Which countries are in the MENA region

A commonly used core list includes:

Area Countries usually included
Gulf and Arabian Peninsula Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, United Arab Emirates, Yemen
Levant and eastern Mediterranean Israel, Jordan, Lebanon, Palestine, Syria
Mesopotamia and Iran Iraq, Iran
North Africa Algeria, Egypt, Libya, Morocco, Tunisia
Sometimes added Djibouti, Malta, Mauritania, Somalia, Sudan, Turkey, Western Sahara

Israel is included in standard definitions even though it is not an Arab state and its economy differs sharply from its neighbors. Turkey is a classic borderline case; some analysts use “MENAT” to make its inclusion explicit. India (South Asia) and Nigeria (West Africa) do not appear in common MENA definitions.

How the term is used

Statistics and development data

International organizations publish regional aggregates for MENA, such as total GDP, population and growth rates. These aggregates let analysts compare the region with others, such as sub-Saharan Africa or East Asia, and track how it performs over time. Because each organization picks its own membership list, a MENA figure from one source is not automatically comparable with a MENA figure from another.

Investing and business

Fund managers and index providers use MENA, or narrower slices of it, to define investment universes. Multinational companies often run a “MENA” or broader “MEA” (Middle East and Africa) division, which may include all of Africa rather than only the north.

  • GCC (Gulf Cooperation Council): a formal political and economic union of six states: Saudi Arabia, the UAE, Kuwait, Qatar, Bahrain and Oman. All are in MENA, but MENA is much larger.
  • Arab world / Arab League: defined by language and membership in the Arab League, not geography. It includes countries outside typical MENA lists (such as the Comoros) and excludes MENA members such as Israel and Iran.
  • MEA: Middle East and Africa, a corporate sales region covering the whole continent.
  • MENAP: MENA plus Afghanistan and Pakistan, used in some international economic reporting.
  • OPEC: a producers’ cartel defined by membership, not region. Seven of its 12 members are in MENA, while others are in Africa south of the Sahara and in South America.

MENA is also unlike groupings such as BRICS, which is a club of countries that chose to coordinate. Nobody joins MENA; analysts place countries in it.

Worked example: why the definition changes the numbers

Hypothetical figures, for illustration only. Suppose an analyst builds a regional total from four economies:

Economy GDP (hypothetical)
Country A $800 billion
Country B $400 billion
Country C $200 billion
Borderline Country D $900 billion

Under a narrow definition that excludes Country D, regional GDP is $800 + $400 + $200 = $1.4 trillion, and Country A is the largest economy with a 57% share ($800 ÷ $1,400). Under a broad definition that includes Country D, the total becomes $2.3 trillion, Country D is now the largest economy, and Country A’s share falls to about 35% ($800 ÷ $2,300).

Nothing about Country A changed, yet its rank and share did. The same happens with real MENA data when a large borderline economy such as Turkey is added or dropped. Before comparing growth rates, shares or rankings from different sources, check which countries each source counted. Results also shift depending on whether GDP is measured at market exchange rates or at purchasing power parity.

Oil and gas reserves

The region’s global importance rests largely on hydrocarbons. MENA holds more than half of the world’s proven oil reserves and about 40% of its natural gas reserves. Saudi Arabia alone controls the world’s second-largest proven oil reserves. This concentration means that output decisions, infrastructure disruptions or conflict in the region can move global energy prices, which in turn feed into inflation measures such as the Consumer Price Index in importing countries.

Heavy reliance on one commodity also creates a specific vulnerability. Hypothetical example: if oil and gas make up 40% of an economy’s output and hydrocarbon revenue falls by 25% while everything else holds steady, the economy’s nominal output drops by about 10% (40% × 25%). Diversification efforts across the region are largely about shrinking that 40% so that a price shock does less damage.

Major economies in MENA

The figures below are World Bank GDP data for 2025 in current U.S. dollars.

Saudi Arabia

Saudi Arabia is the largest economy in the region, with 2025 GDP of $1.28 trillion. Petroleum and natural gas make up roughly 40% of GDP. The government has announced plans to reduce dependence on oil exports by investing in technology and tourism.

Israel

Israel’s 2025 GDP was $610.78 billion, making it the second-largest MENA economy. Unlike most of its neighbors, it is not an energy exporter. Its economy is built on industrial manufacturing, diamond cutting and trading, and high technology. Israel ranks among the leading global high-tech ecosystems and is often called the “start-up nation,” with the highest number of start-ups per capita in the world. It combines high average incomes and a strong currency with repeated conflict involving its neighbors.

Egypt

Egypt recorded 2025 GDP of $365.26 billion, making it the largest economy in North Africa and the fifth largest in MENA. Its main sources of income are tourism, remittances from Egyptians working abroad, agriculture and natural gas exports. Infrastructure spending and economic reforms have supported growth since 2011, but the country has struggled with high inflation and shortages of foreign currency.

Iran

Iran’s 2025 GDP was $362.68 billion, placing it sixth in the region. Its economy depends on petroleum exports but is more diversified than other Middle Eastern oil exporters. International sanctions tied to its nuclear program, its designation by the U.S. as a state sponsor of terrorism, and cyber activity against other countries heavily restrict its trade. Its currency has lost much of its value.

Gulf diversifiers

Several smaller Gulf economies are working to move beyond fossil fuels. The United Arab Emirates has a growing technology sector, and Qatar is expanding its financial services industry.

Is MENA developed or developing?

Neither label fits the whole region. MENA contains high-income economies, such as Israel and several Gulf states, alongside lower-income countries and economies damaged by war. Analysts usually assess countries individually or in subgroups such as the GCC.

Investing in MENA

Because most of the region’s economic weight is in energy, many investment opportunities are tied to oil and gas. U.S. investors have typically gained exposure through country or sub-regional funds rather than a single fund covering every MENA country. Examples include the iShares MSCI Saudi Arabia ETF (KSA), iShares MSCI Kuwait ETF (KWT), iShares MSCI UAE ETF (UAE), iShares MSCI Qatar ETF (QAT) and iShares MSCI Israel ETF (EIS). The VanEck Africa Index ETF (AFK) covers the whole African continent, so North Africa is only part of its exposure. Investors outside the U.S. may have access to different region-specific funds.

Country funds behave very differently from one another. A Saudi or Qatari fund is closely linked to energy prices and state-related companies, while an Israel fund leans toward technology.

Geopolitical risk

The strategic value of the region’s oil has drawn both local conflict and outside intervention. The U.S. invasions of Iraq and Afghanistan disrupted regional economic activity, and the 2011 Arab Spring protests led to revolutions and civil wars in several countries. Other sources of instability include the Israeli-Palestinian conflict, wars in Syria, Yemen and Iraq, political instability in Lebanon, and the rivalry between Iran and Saudi Arabia.

For the economy, conflict can damage energy infrastructure, disrupt supply and shipping routes, raise volatility in oil and financial markets, and slow growth. For investors, it adds political and sanctions risk on top of ordinary market risk.

Limitations of the MENA label

  • No fixed membership. Aggregates and rankings depend on which of the 19 to 27 countries a source counts.
  • Huge internal differences. Oil-rich Gulf monarchies, a technology-driven Israel, populous Egypt and sanctioned Iran share a label but little economic structure.
  • Geography over economics. The grouping is based on location, so it can mislead when used as a proxy for energy exposure, income level or political alignment.
  • Overlap with other groupings. MENA, the Arab world, the GCC, MEA and OPEC overlap without matching, so mixing their data produces errors.

The Bottom Line

MENA matters to anyone reading regional economic data, tracking energy prices or investing in the area. Because sources count different countries, check each membership list before comparing totals, shares or rankings. U.S. investors usually reach the region through country funds, and those funds behave very differently, with Saudi and Qatari funds tied to energy and an Israel fund leaning toward technology.
