The 2008 MLS Expansion Draft took place on November 26, 2008, and was a special draft for the Major League Soccer expansion team Seattle Sounders FC. They made 10 selections from a pool of players from the other 14 MLS clubs.
Only one player could be selected from each team. Four of the league's 14 current teams did not have a player selected.
Teams were allowed to protect 11 players from their 28-man rosters. Generation Adidas players were automatically protected, though players who are graduated from the program to the senior roster at the end of the 2008 season were not.
Teams with 4 or more international players were required to protect 3 of them. If a team had 3 or fewer international players, then it was required to protect all but one.
Any developmental players selected were required to be moved up to the senior roster for the 2009 season.
