The 1973–74 UEFA Cup was the third season of the UEFA Cup, the third-tier club football competition organised by UEFA. The final was played over two legs at White Hart Lane, London, England, and at De Kuip, Rotterdam, the Netherlands. It was won by Feyenoord of the Netherlands, who defeated Tottenham Hotspur of England by an aggregate result of 4–2 to claim their first UEFA Cup title. This was the fifth consecutive year where a Dutch team won a European competition, and the first one outside of the European Cup. Feyenoord also broke a streak of six consecutive years of English clubs winning the UEFA Cup or the Inter-Cities Fairs Cup.
