2008–09 Guatemalan Liga Nacional

The 2008–09 Guatemalan Liga Nacional season was the 10th season in which the Apertura and Clausura format was used.

The season was divided into two tournaments; the Apertura, which is played from August to December, and the Clausura, which is played from January to May. The first six clubs in the standings at the end of each competition participate in the playoffs (a two-leg knock-out phase) to determine the champion; the first and second place teams qualify directly to the semi-finals, while the other two have to play in the quarter-finals. The winners of the Apertura and Clausura tournaments participate in the 2009–10 CONCACAF Champions League.
