Ajax Rock City, an amateur football club from the Mathare neighbourhood of Nairobi, was founded after violence and unrest following Kenya's 2007 elections to bring young people together and offer positive engagement. The club also carries out social work in the community and its first team plays in a local amateur league with 15 other Mathare clubs.

The club was initially called Rock City and added Ajax to its name and its current logo a year later, citing inspiration from Ajax Amsterdam's emphasis on developing young talent. The two clubs have no formal relationship, and Ajax Rock City has no official permission from Ajax Amsterdam to use its name or logo. Its chief executive said the club uses them out of admiration for the Dutch club.
