The site was originally used by pastoralists and traders.

The modern city began in 1898. Colonial authorities established it as a rail depot for the Uganda–Kenya Railway. Sir George Whitehouse, the chief engineer, chose this specific site. He wanted a resting place for Indian laborers working on the railway. He liked the high elevation and the temperate climate. He also noted the adequate water supply. The railway arrived on May 30, 1899. The town grew quickly and replaced Mombasa as the capital in 1907. Later, after Kenya gained independence in 1963, Nairobi remained the capital of the Republic of Kenya.

Nairobi has experienced massive population growth. In 1902, the population was only 5,000. By 1910, it had risen to 16,000. In 1921, there were 24,000 residents. By 2024, the city's population reached 4.8 million. The metropolitan population is even larger at 5.7 million.
