Isla Darwin (Darwin, or Culpepper Island) was named after famous biologist Charles Darwin. It is one of the Galápagos Islands and it measures 1.1 km² (0.42 sq mi). Its highest point is 168 m (551 ft) above sea level.

Animals that roam the island and its surrounding waters include fur seals, frigates, marine iguanas, swallow-tailed gulls, sea lions, whales, marine turtles, red-footed boobies and Nazca boobies. The landmark natural rock arch named Darwin's Arch used to be located several hundreds of meters off the island's coast, but it collapsed in 2021. Only the 2 'pillars' now remain, which are called the 'Pillars of Evolution'.
