The Campeonato de Apertura, also the Torneo TIGO Apertura for sponsorship reasons, is the first championship of the season. It began on February 14 and ended on July 5.

The two tournament champions earn the Paraguay 1 and Paraguay 2 berths in the Second Stage of the 2010 Copa Libertadores. All remaining international qualification will be determined through a season-wide aggregate table. The Paraguay 3 in the 2010 Copa Libertadores berth goes to the best-placed non-champion. For the 2010 Copa Sudamericana, the Paraguay 1 berth goes to the highest placed champion. Paraguay 2 and Paraguay 3 will go to the highest placed teams who have not qualified to an international tournament.
Relegations is determined at the end of the season by computing an average (Spanish; Castilian: promedio) of the number of points earned per game over the past three seasons. The team with the lowest average is relegated to the División Intermedia for the following season. The next lowest team plays a relegation/promotion playoff match against the 2009 División Intermedia runner-up.

Should there be a tie in points, goal difference was taken into account, followed a penalty shootout if needed. Sport Colombia played at home during the second leg.
