The 2007 UEFA Champions League final was the final match of the 2006–07 season of the UEFA Champions League, Europe's primary club football competition. The showpiece event was contested between Liverpool of England and Milan of Italy at the Olympic Stadium in Athens, Greece, on 23 May 2007. Liverpool, who had won the competition five times, were appearing in their seventh final. Milan, who had won the competition six times, were appearing in their eleventh final.

The final was a rematch of the 2005 final which Liverpool won 3–2 in a penalty shootout, after recovering from a three-goal deficit at half-time to level the score at 3–3 after full-time and extra time. Both teams had to pass through five rounds before they reached the final. They both entered in the third qualifying round and won their respective groups before they reached the knockout stage, where matches were contested over two legs, with a match at each team's home ground. Milan's victories varied from close affairs to comfortable victories. They defeated Celtic by a single goal over two legs, while they beat Manchester United 5–3 on aggregate in the semi-final. Liverpool's matches were mainly all close affairs; they beat defending champions Barcelona on the away goals rule in the first knockout round and beat Chelsea in a penalty shootout in the semi-finals, although they did record a 4–0 aggregate win over PSV Eindhoven in the quarter-finals.

Before the match there were ticketing problems because many fans gained entry to the stadium without valid tickets. After the match, a UEFA spokesman accused Liverpool of having the worst fans in Europe, a claim later denied by UEFA president Michel Platini. Watched by a crowd of 63,000, Milan took the lead when Andrea Pirlo's free-kick deflected off Filippo Inzaghi in the first half. Milan extended their lead in the second half when Inzaghi scored a second goal. Liverpool scored a late goal through Dirk Kuyt, but were unable to equalise before the end of the match. Milan won the match 2–1 to win their seventh Champions League.

The match was Milan's eleventh appearance in the final, and the third since 2003. They had won on six occasions (1963, 1969, 1989, 1990, 1994, 2003), and lost four times (1958, 1993, 1995, 2005). Liverpool were appearing in their seventh final. They had previously won the competition five times (1977, 1978, 1981, 1984, 2005), while they lost the 1985 final to Juventus.

The Olympic Stadium in Athens, Greece was selected as the venue for the 2007 UEFA Champions League final at the April 2005 meeting of the UEFA Executive Committee in Tallinn, Estonia. The meeting also determined the venues for the 2006 final and the 2006 and 2007 UEFA Cup finals. Shortly before the final, the UEFA Champions League trophy was returned to UEFA by Ludovic Giuly, representing the 2006 winners, Barcelona. UEFA president Michel Platini then presented the trophy to the Mayor of Athens, Nikitas Kaklamanis, so that it might be put on display in and around the city. The stadium had hosted the showpiece event before. The most recent was the 1994 final. Coincidentally Milan were the winners, beating Barcelona 4–0. The other final held at the ground was in 1983, when Hamburger SV beat Juventus 1–0. The ground had also played host to the UEFA Cup Winners' Cup final in 1987, when Ajax beat Lokomotiv Leipzig 1–0.

Milan qualified for the competition by finishing third in the 2005–06 Serie A. Milan had originally finished second in Serie A, but were docked 30 points for their part in a match-fixing scandal. The original punishment, reduced on appeal, would have barred them from the Champions League altogether. Their opponents in the third qualifying round were Serbian team Red Star Belgrade. Two victories, 1–0 at home and 2–1 away, ensured Milan's passage to the group stage of the Champions League. They were drawn in Group H alongside AEK Athens of Greece, Anderlecht of Belgium and French team Lille. Milan won three matches, drew one and lost two to finish top of the group with 10 points and progress to the knockout stage.

They were drawn against Scottish team Celtic. The first leg at Celtic's home ground Celtic Park finished 0–0. The return leg at Milan's home ground the San Siro also finished 0–0 after 90 minutes with Celtic managing to limit the goalscoring opportunities Milan had. However, three minutes into extra time Milan scored when Kaká curled a shot past Celtic goalkeeper Artur Boruc. Celtic were unable to score the away goal they needed to beat Milan, ensuring the Italians progressed to the quarter finals after a 1–0 aggregate victory.

Milan were drawn against German team Bayern Munich in the quarter-finals. The first leg at the San Siro ended in a 2–2 draw after Bayern had scored an equaliser three minutes into stoppage time. The second leg at Bayern's home ground the Allianz Arena was more comfortable for Milan, as they scored two first half goals to win the match 2–0 and win the tie 4–2 on aggregate. Milan were drawn against English team Manchester United in the semi-finals. The first leg at United's home ground Old Trafford, Kaka scored twice to give Milan a 2–1 lead after Cristiano Ronaldo had scored an early goal. However, two goals from Wayne Rooney in the second half meant United won the first leg 3–2. The second leg at the San Siro saw Milan win 3–0 to progress to the final after a 5–3 aggregate victory.
