The 2010 Primera División del Fútbol Profesional Chileno season (known as the 2010 Campeonato Nacional Petrobras for sponsorship reasons) was the 79th season of top-flight football in Chile. Originally comprising two tournaments, the 2010 season was the first single-stage season since 2001. This was due to the devastating 8.8 magnitude earthquake on February 27, 2010. Universidad Católica won their tenth title. Format changes Due to Chile's qualification to the 2010 FIFA World Cup, the format for the season had seen a minor modification in the Apertura, which would not have the playoff stage.

After the Round 1 (the first 17 dates), the team with the most points qualified to the 2010 Copa Sudamericana and the 2011 Copa Libertadores. The next best-placed team played a playoff against Municipal Iquique for the last berth in the 2010 Copa Sudamericana. The season champion (the team with the most points after all 34 dates)
