In which country did Charles Darwin die?

Charles Darwin died in England. He died at Down House, his family home in Downe, Kent, on 19 April 1882, at the age of 73.

Darwin had spent decades developing and defending his theory of evolution by natural selection. Although he suffered from recurring illness for much of his adult life, he continued publishing influential work on plants, animals, human evolution, and scientific method.

His death place is sometimes confused with the locations associated with his travels. Darwin spent nearly five years aboard HMS Beagle, visiting South America, the Galápagos Islands, Australia, and other regions. Those journeys shaped his evolutionary thinking, but he did not die in any of those places.

Darwin was buried in Westminster Abbey in London, alongside other notable British scientists. Thus, England is the country in both the geographic and historical sense intended by the question; Wales, Ireland, and Scotland are separate countries within the United Kingdom and are not where he died.
