Meaning & origin

Nairobi entered the U.S. baby name charts in 1983, making it one of the newer city-inspired names. It reached its highest rank of 1867 in 2021, but has since fallen in popularity. As of 2025, about 1 in 15163 girls receive the name. The name has been most popular in Georgia, Florida, and North Carolina. Nairobi's appeal lies in its connection to the vibrant capital of Kenya, evoking images of wildlife and natural beauty. Despite its recent decline, the name retains a modern, worldly feel that sets it apart from more traditional choices.

Nairobi is a modern given name taken directly from the capital city of Kenya. The city's name originates from the Maasai phrase 'Enkare Nyirobi', which translates to 'cool waters', referring to the Nairobi River that flows through the area. The name first saw use as a personal name in the United States in 1983, likely inspired by the city's prominence and exotic appeal.
