Congo Ligue 1 is the top division of the Congolese Football Federation, in the Republic of the Congo. It was created in 1961. The official name is Championnat National MTN for sponsorship reasons.
Between 1961 and 1977 the championship was decided in a 3-team tournament between the regional champions of Brazzaville, Pointe-Noire, and Niari. From 1978 to 1993, a nationwide league with 10 to 14 teams was played. From 1994 to 2008, the FECOFOOT reverted to a national play-off after the regional tournaments, with additional entries for the stronger leagues (Brazzaville, Pointe-Noire). In 2009, a nationwide league was reformed with 18 teams.
