2005–06 Celtic F.C. season

Celtic started the season 2005–06 looking to win the Scottish Premier League trophy and retain the Scottish Cup. They competed in the Scottish League Cup, and entered the Champions League at the qualification stage.

Celtic were knocked out of the Scottish Cup in the third round by Clyde, losing 2–1. They won the Scottish League Cup with a comfortable 3–0 victory over Dunfermline on 19 March 2006, while the league was regained after a 1–0 win over Hearts. Rival managers were quick to praise the manner in which Celtic had regained the SPL title.
