FC Santa Coloma were the defending champions, having won their fifth Andorran championship last season.
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.
They were replaced by Segona Divisió champions Casa Estrella del Benfica.
FC Encamp finished seventh in the league and will compete in a two-legged relegation playoff against UE Engordany, the third place team of the Segona Divisió, for one spot in 2011–12 Primera Divisió.
Engordany won the playoff, 5–1 on aggregate, and were promoted to the Primera Divisió while Encamp were relegated.
