The THB Champions League is the premier football league in Madagascar. The competition is played in a round-robin format between the 24 qualifying clubs from the 22 regional leagues in the country. In each of the four rounds, the teams are divided into groups of four teams, with each team playing the others once and with the top two clubs in each group advancing to the next round. In the final round, the winner of the last group (the "groupe des As") is the champion.
