Solomon Islands National Club Championship

The Solomon Islands S-League or Telekom S-League for sponsorship reasons, previously known as the Solomon Islands National Club Championship, is the top division of the Solomon Islands Football Federation in Solomon Islands.

Format
The teams play a double round robin to decide the S-League champion. All teams of the league also play a knockout tournament after the season, the NSL Championship. The winners of both competitions play a two legged playoff for a place in the OFC Champions League. Both titles are awarded with a 150,000$ price. Should a team win both competitions, it is automatically qualified for the Champions league.

National club championship
The first national club championship was held in 2003.

Telekom S-League

Eleven teams applied for eight places in the initial season, namely Marist, Koloale, KOSSA, Solomon Warriors, Makuru, Northern United, Central United and Hana from Honiara; Western United from Western Province, Sokamora from Makira Ulawa Province and Fasi Roos from Malaita Province. The clubs whose applications were accepted by the Solomon Islands Football Federation finally were: Marist, Koloale, KOSSA, Solomon Warriors, Makuru, Hana, Western United and Fasi Roos.
