The 2006–07 UEFA Champions League was the 15th season of UEFA's premier European club football tournament, the UEFA Champions League, since it was rebranded from the European Cup, and the 52nd season overall. The final was contested by Milan and Liverpool on 23 May 2007. Beforehand, the match was billed as a repeat of the 2005 final, the only difference being that the 2007 final was to be played at the Olympic Stadium in Athens, Greece. Milan won the match 2–1 to claim their seventh European Cup, with both goals coming from Filippo Inzaghi. Dirk Kuyt scored for Liverpool.
Barcelona were the defending champions, but were eliminated by Liverpool in the first knockout round.
On 8 February, the Italian Government announced that San Siro Stadium in Milan was unsafe for spectators in light of riots that took place during and following an Italian Serie A match in Sicily. As a result, the venues of the first leg of the Inter-Valencia tie scheduled for 21 February and the second leg of the Celtic-Milan tie scheduled for 7 March were thrown into doubt. Various proposals and offers of the use of stadia outside Italy were made, but it was finally agreed that the Inter-Valencia tie would be played at the San Siro with a reduced capacity of 36,000. After further work at the San Siro, Italian authorities and UEFA announced that the second leg of Celtic-Milan would go ahead at the stadium, at its full capacity of 85,700. 4,500 seats were reserved for Celtic supporters.

The draw for this round was held on 24 August 2006 in Monaco. The first matches were played on 12 September 2006, and the stage concluded on 6 December.
The top two teams in each group advanced to the knockout stage, and the third-placed teams entered the round of 32 of the UEFA Cup. Based on paragraph 4.05 in the UEFA regulations for the current season, if two or more teams are equal on points on completion of the group matches, the following criteria are applied to determine the rankings:
higher number of points obtained in the group matches played among the teams in question;
superior goal difference from the group matches played among the teams in question;
higher number of goals scored away from home in the group matches played among the teams in question;
superior goal difference from all group matches played;
higher number of goals scored in all group matches played;
higher number of coefficient points accumulated by the club in question, as well as its association, over the previous five seasons.
All knockout rounds are two-legged, except for the final. In the event of aggregate scores being equal after normal time in the second leg, the winning team will be that which scored more goals on their away leg: if the scores in the two matches were identical, extra time is played. The away goals rule also applies if scores are equal at the end of extra time. If there are no goals scored in extra time, the tie is decided on a penalty shoot out.
The draw for the first knockout round of the competition took place on 15 December 2006 in Nyon, Switzerland. The team first out of the hat in each tie plays the first leg of their tie at home, and the second leg away. This team is denoted as "Team #1" below.
