In international relations, regional power, since the late 20th century has been used for a sovereign state that exercises significant power within its geographical region.^[1][2] States that wield unrivaled power and influence within a region of the world possess regional hegemony.

Regional powers shape the polarity of a regional area. Typically, regional powers have capabilities which are important in the region, but do not have capabilities at a global scale. Slightly contrasting definitions differ as to what makes a regional power. The European Consortium for Political Research defines a regional power as 'a state belonging to a geographically defined region, dominating this region in economic and military terms, able to exercise hegemonic influence in the region and considerable influence on the world scale, willing to make use of power resources and recognized or even accepted as the regional leader by its neighbors.'^[1]

The German Institute of Global and Area Studies states that a regional power must:^[2]

• Form part of a definable region with its own identity
• Claim to be a regional power (self-image as a regional power)
• Exert decisive influence on the geographic extension of the region as well as on its ideological construction
• Dispose over comparatively high military, economic, demographic, political, and ideological capabilities
• Be well integrated into the region
• Define the regional security agenda to a high degree
• Be appreciated as a regional power by other powers in the region and beyond, especially by other regional powers
• Be well connected with regional and global forums

In this list are states that have been described as regional powers by international relations and political science academics, analysts, or other experts. These states, to some extent, meet the criteria for regional power status, as described above. Different experts have differing views on exactly which states are regional powers. States are arranged by their region, and in alphabetical order.

Even though the economic weight of Africa is relatively low compared to other continents, and more than two-thirds of African countries are among the least developed states in the world, Africa's rich natural resources and diverse cultures could carry the potential to enable future development.

Although South Africa was diplomatically isolated during the latter years of the apartheid era, it is considered to have successfully reintegrated into international affairs over the last 20 years. It is recognized as the only newly industrialized country in Africa and takes a crucial role in BRICS and G20.

Nigeria is often referred to as the "Giant of Africa" due to both its population and economy being the largest in Africa and the cultural influence that it holds over other countries in Sub-Saharan Africa through its movie industry and mass media. Nigeria is also the largest oil producer in Africa.

Nigeria and South Africa are among the largest African economies; both have GDPs over $250 billion (nominal) and $700 billion (PPP) as of 2020.

Historically, Imperial China was the dominant power in East Asia. From the late 19th century, the Empire of Japan initiated far-reaching Westernizing reforms, and rapidly industrialized, to become a major power in Asia by the time of World War I, as one of the Allied powers. With economic turmoil, Japan's expulsion from the League of Nations, and its interest in expansion on the mainland, Japan became one of the three main Axis powers in World War II.^{[citation needed]}

Since the late 20th century, regional alliances, economic progress, and contrasting military power changed the strategic and regional power balance in Asia. In recent years, a re-balancing of military and economic power among emerging powers, such as China and India, has resulted in significant changes in the geopolitics of Asia. China and Japan have also gained greater influence over regions beyond Asia. In recent decades, South Korea has emerged as a significant economic and cultural power in East Asia. Japan and South Korea are important allies for the United States in the Indo-Pacific region.

Russia – the dominant part of a former superpower, the Soviet Union, is now considered a potential superpower, and has historically been the primary geopolitical force in Eastern Europe. France, Germany, Italy, and the United Kingdom, collectively known as Big Four in Western Europe, as they play pivotal roles as part of the NATO Quint in the security of the Western Bloc. Most of the continent is now integrated as a consequence of the enlargement of the European Union, which is sometimes considered a great power as a whole, despite it not being a sovereign state.^[20][21] Historically, dominant powers in Europe created colonial empires (such as the Belgian, British, Danish, Dutch, French, German, Italian, Portuguese, Russian, and Spanish Empires).

The United States is the primary geopolitical force in North America, and is widely considered as the sole contemporary superpower globally. It dominates the region so heavily that its neighbors, Canada and Mexico, both middle powers in the region, are generally not considered regional powers. Despite having a large enough economy to be a member of the G7, Canada is not a regional power for two reasons. It is militarily secure as a result of U.S. hegemony, and has become financially comfortable by its dependence on, and deep integration with, a robust U.S. economy.^[30] Mexico is an emerging power which could probably be viewed as a regional power if grouped with Latin America, or a definite regional power if considered in either Middle America or in Hispanic America due to its economic size and diverse cultural heritages.^[31] However, similar to Canada, Mexican economy is highly reliant on the U.S. with about 80% of its exports shipping to the U.S. alone.^[32][33]

Australia is considered to be a regional power due to its significant commercial and diplomatic relations in Asia–Pacific region since the late 1990s.^[34]

Since the Age of Discovery, Portugal and Spain mostly divided South America to be the foremost colonial powers in the continent, but following decolonization in the first half of the 19th century, the European powers withdrew and new nations were established, although their cultural influence and languages still remain predominant in Latin America.

Brazil is considered one of the most compelling geopolitical power in South America, as the country has the highest population and landmass in the continent, and its economic size, which possesses large stockpiles of natural resources, including valuable minerals, a tenth of the world's fresh water and it's also one of the countries that contain the Earth's largest remaining rainforest. Brazil has an important role in international relations, especially in economic and global environmental issues.^[36]
