The 2012–13 Primera Divisió is the eighteenth season of top-tier football in Andorra.
The defending champions are FC Lusitanos, who won their first championship in the previous season.
[1] The participating teams first played a conventional round-robin schedule with every team playing each opponent once "home" and once "away" (in actuality, the designation of home and away was purely arbitrary as the clubs did not have their own grounds) for a total of 14 games.
FC Rànger's were relegated after last season due to finishing in 8th place.
Inter Club d'Escaldes, who finished last season in 7th place, and 2nd place Segona Divisió club UE Extremenya played a two-legged relegation play-off.
