The Nairobi derby (also known as the Shemeji derby and the Kenya derby and lately as the Ingo-Dala derby) is the name of the football local derby between the two major teams in Nairobi; A.F.C. Leopards and Gor Mahia. It is considered the oldest, the most intense, the most famous and the most bitter rivalry of all time in the history of Kenyan football. Fans of both A.F.C. Leopards and Gor Mahia (often referred to by their nicknames, Ingwe and Kogalo, respectively) recognize each other as archrivals. AFC Leopards has won the Kenyan Premier League a record 13 times, one better than Gor's 12 titles.
As of 17 November 2012, A.F.C. Leopards have beaten Gor Mahia 25 times, while Gor Mahia have beaten A.F.C. Leopards 21 times. All of the 27 other derby matches between the two teams ended in draws.
The two clubs have been bitter rivals since the league's inception in 1963. In a match on 23 March 2012, Gor Mahia fans began to riot after defender Ali Abondo was given a red card following a dangerous tackle on Leopards' Amon Muchiri. Gor Mahia was banned by the Sports Stadia Management Board from using their facilities for the rest of the 2012 season (those being the Nyayo National Stadium and the Kasarani Stadium) as a result. This was also the reason for the postponing of their Round of 8 derby match in the 2012 KPL Top 8 Cup.
