The Nairobi Marathon is an annual road running competition over the marathon distance usually held in October in Nairobi, Kenya. First held in 2003, the competition expanded and now includes a half marathon race along with the main race.
It was part of "The Greatest Race on Earth", fully sponsored by Standard Chartered Bank. The other three legs of this four-marathon race were the Hong Kong Marathon, the Mumbai Marathon and the Singapore Marathon.
The 2020 edition of the race was cancelled due to the coronavirus pandemic.
