The 2011 season was Dundalk's third successive season in the League of Ireland Premier Division following promotion in 2008. Altogether, it was the club's 85th season in League of Ireland football. The club was managed by Ian Foster, who was in his second season in charge. The club finished the 36-match season in 7th position having been challenging at the top of the table for the first half of the season. The club also competed in the FAI Cup, League of Ireland Cup, Setanta Sports Cup, and the Leinster Senior Cup. In the Setanta Sports Cup they reached the final, but lost to Shamrock Rovers F.C.
After losing the final, and with the playing budget already being restricted by the club's owner, Gerry Matthews, results subsequently deteriorated as the season drew to a close. Financial losses were mounting, and Matthews decided to relinquish control of the club. Foster's contract expired at the end of the season and he was allowed to leave.
