The 2010 Los Angeles Galaxy season was the club's fifteenth season of existence. It was also the Galaxy's fifteenth season in Major League Soccer and their fifteenth-consecutive year at the top-flight of American soccer.
The club's season was highlighted by winning their third-ever Supporters' Shield. Statistically, the 2010 MLS season was the Galaxy's strongest season on record, and the club had their strongest start ever, opening their first eleven games unbeaten before losing to the eventual second-place finishers, Real Salt Lake at Rio Tinto. Some of the club's notable achievements included Edson Buddle being a runner-up for the MLS Golden Boot award, with 17 goals tallied during the regular season. Galaxy captain and United States national team star Landon Donovan led the club in assists with 12. The club finished the MLS regular season with a 17–7–8 record, their best in nearly a decade.
The club also competed in the preliminary rounds of the CONCACAF Champions League, and the early rounds of the U.S. Open Cup.
In Champions League play, the Galaxy, considered at one point to be favorites to win the entire tournament suffered a shocking blow, when the club suffered a 4–1 home defeat to confederation minnows, Puerto Rico Islanders, who were 11th place at the time in USSF D2 Pro League, the then-second tier of U.S. soccer. Although the Galaxy would defeat the Islanders 2–1 in Puerto Rico, it was not enough on aggregate to see the club advance into Group play. In the tournament, the Galaxy were the only club to defeat the Islanders in Puerto Rico. However, the Galaxy returned to Champions League play the next year by winning the Supporters' Shield title.
The Galaxy made it to the quarterfinals of the U.S. Open Cup with a convincing 2–0 win over second-tier AC St. Louis, before losing to Seattle Sounders FC by the same score line.
