2008 Colorado Rockies season

The Colorado Rockies' 2008 season was the team's 16th season overall. The Rockies attempted to repeat their previous season's success after making it to the World Series; however, they ended up finishing third place in the National League West with a record of 74-88. The Rockies drew 2,650,218 fans for the season, their highest total since 2002. The average home attendance was 33,127 fans.

Likely the most memorable game of the year was against the San Diego Padres on April 17, as it went 22 innings before Troy Tulowitzki drove in the winning run. It is the longest Rockies game in franchise history and (as of 2024) the longest game of the 21st century.
