Primera División de Fútbol Profesional – Apertura 2009

The Apertura 2009 season (officially known as Torneo Apertura 2009) was the twenty-third tournament of the Primera División de Fútbol Profesional since its establishment of an Apertura and Clausura format. FAS won the tournament for the 17th time in history, defeating Águila in the finale with a 3–2 victory in extra time. Isidro Metapán were the defending champions, having won their 3rd title the previous season and being the back to back champions. A total of 10 teams contested the league, with none getting relegated (relegation only occurs on Clausuras). The season began on August 14, 2009 and concluded on December 20, 2009. The 10 teams of the Primera División played 18 matches, playing each team twice (home and away). The top four teams qualified directly to the semifinals. Since Vista Hermosa and Isidro Metapán finished with the same points at the end of the regular season, a knockout playoff match was played to determine the last team to advance to the playoffs. Vista Hermosa clinched the final spot for the playoffs with a 1–0 victory over Isidro Metapán.
