The 1973 UEFA Cup final was played over two legs at Anfield, Liverpool, England, and at Bökelbergstadion, Mönchengladbach, West Germany.

It was won by Liverpool of England, who defeated West German team Borussia Mönchengladbach by an aggregate result of 3–2 to claim their first UEFA Cup title.

This was the sixth consecutive title won by an English team between the UEFA Cup and the Inter-Cities Fairs Cup, as well as the first time Liverpool won a European competition.

A new allocation scheme was devised by UEFA, which featured fixed slots for all but two competing associations, and lasted for eight seasons: Spain was the only association with a fixed allocation of three teams; the other two associations would rotate on a yearly basis among all countries that were allocated two teams.

Albania was not included in this scheme, as it had only entered the competition once without playing and would not have a UEFA Cup competitor until 1981.

Northern Ireland withdrew from the competition, so another association was granted an extra third birth for this season.

The three chosen associations were France, Yugoslavia and Portugal.
