Megadiverse countries are a group of countries that harbor the majority of the Earth's species and are therefore considered extremely biodiverse. Conservation International identified 17 megadiverse countries in 1998. All are located in, or partially in, tropical or subtropical regions.

In 2002, Mexico formed a separate organization focusing on Like-Minded Megadiverse Countries, consisting of countries rich in biological diversity and associated traditional knowledge. This organization does not include all the megadiverse countries as identified by Conservation International.

In alphabetical order, the 17 megadiverse countries are:

 Australia
 Brazil
 China
 Colombia
 Democratic Republic of the Congo
 Ecuador
 India
 Indonesia
 Madagascar
 Malaysia
 Mexico
 Papua New Guinea
 Peru
 Philippines
 South Africa
 United States
 Venezuela

Some areas in our planet are richer in biodiversity than others. Those areas with a higher density of different species are not necessarily where the environment is best protected –it is rather thanks to the type of ecosystem. Tropical rainforests are the top biodiversity-rich ecosystems: only the Amazon rainforest harbours one out of every ten known species of our planet.

Therefore, some countries have a major responsibility to protect this diversity, so the World Conservation Monitoring Centre of the UN Environment Programme (UNEP-WCMC) has been working on this issue since 1988. Up to now, it has identified 17 megadiverse countries, that is, those countries with the highest number of endemic species –at least 5,000 endemic plants.

The world’s top biodiversity-rich continent is America, with 7 megadiverse countries:

- Brazil
- Colombia
- Ecuador
- Unites States
- Mexico
- Peru
- Venezuela

Asia ranks the second, with 5 megadiverse countries:

- The Philippines
- India
- Indonesia
- Malaysia
- China

Africa ranks number three, with 3 megadiverse countries:

- Madagascar
- Democratic Republic of the Congo
- Republic of South Africa

Oceania ranks number 4, with 2 megadiverse countries:

- Australia
- Papua New Guinea

Europe has no megadiverse country.
