The 1905-06 season was the edition IV of the Liga Mexicana de Football Amateur Association. San Pedro Golf Club changed its name to Mexico Country Club.
Reforma won the championship, though dominated by British players, did also allow native players. It was remarkable that in 20 league matches there were 16 where at last one or both sides failed to score. The champions had two excellent full-backs in the brothers Robert and Charles Blackmore, while most of their goals were not scored by a forward but by right half-back Charles Butlin.
