Amboseli National Park, formerly Maasai Amboseli Game Reserve, is a national park in Kajiado South Constituency, Kenya. The park is 39,206 hectares (392 km2; 151 sq mi) in size at the core of an 8,000 km2 (3,100 sq mi) ecosystem that spreads across the Kenya-Tanzania border. The local people are mainly Maasai, but people from other parts of the country have settled there attracted by the successful tourist-driven economy and intensive agriculture along the system of swamps that makes this low-rainfall area, average 350 mm (14 in), one of the best wildlife-viewing experiences in the world with 400 species of birds including water birds like pelicans, kingfishers, crakes, hamerkop and 47 raptor species.
The park protects two of the five main swamps, and includes a dried-up Pleistocene lake and semiarid vegetation.
About 240 km (150 mi) southeast of Nairobi, Amboseli National Park is the second-most popular national park in Kenya after Maasai Mara National Reserve.
