As of 2022, roughly 210,000 visitors from the United States arrived in Kenya, the largest number among all other countries. Over 151,000 visitors came from Uganda, while some 123,000 were from Tanzania, both neighboring nations.

As of early 2026, the United States remains the largest single foreign source market for tourism in Kenya, maintaining a trend seen throughout 2024 and 2025. In 2024, the US contributed over 300,000 visitors, accounting for approximately 12.8% of all international arrivals. Following closely behind the US are regional neighbors Uganda and Tanzania, which provide high volumes of cross-border travelers, often for business or short-term visits. The United Kingdom and India also consistently rank in the top five source markets, reflecting Kenya's strong historical and economic ties with these nations. The tourism sector has seen a significant post-pandemic surge, with international visitor numbers hitting record highs in 2024. This growth is driven by the booming "MICE" (Meetings, Incentives, Conferences, and Exhibitions) segment in Nairobi, alongside the traditional appeal of wildlife safaris in the Maasai Mara and the pristine white-sand beaches of the coastal regions like Diani and Mombasa.
