Porto Football Association

The Porto Football Association (Portuguese: Associação de Futebol do Porto; abbreviated as AF Porto) is the district governing body for the all football and futsal competitions in the Portuguese district of Porto. It is also the regulator of the clubs registered in the district.

It was officially founded on 10 August 1912 by the initiative of F.C. Porto and Leixões S.C., who were immediately joined by many other clubs, including some from outside districts. Today it's the largest football district association in the country with 340 clubs and 19.796 athletes in all age categories, 750 referees and organises around games 12.800 per season.

Below the Campeonato de Portugal (Portuguese third level) the competitions are organised at a district level (known in Portuguese as Distritais) with each District Association organising its competitions according to geographical and other factors. AF Porto runs a league competition with four divisions, at the fourth, fifth, sixth and seventh levels of the Portuguese football league system and a cup competition known as Taça AF Porto (since 2013–14). Taça AF Porto winners and Elite Division runner-ups earn a spot in the following season's Taça de Portugal.
