1972–73 S.L. Benfica season
The 1972–73 season was Sport Lisboa e Benfica's 69th season in existence and the club's 39th consecutive season in the top flight of Portuguese football, covering the period from 1 July 1972 to 30 June 1973. Benfica competed domestically in the Primeira Divisão and the Taça de Portugal, and participated in the European Cup after winning the previous league.

After securing back-to-back league titles, Jimmy Hagan remained for a third year. Benfica signed Manuel Bento, Nelinho and brought back Augusto Matine. A late start to the pre-season did not hurt Benfica domestically, who started his league campaign with easy wins. However, in the European Cup, after passing Malmö FF, they lost 3–0 on aggregate with Derby County in the second round and were knocked-out. Leaving only the domestic competitions to battle for, Benfica kept his winning pace and recorded win after win, despite difficult wins against Porto in November and CUF in December. Lapping the first half of the season with 15 wins in 15 games, Benfica already had an eight-point lead over second place Belenenses. Another hard-fought win followed with Beira-Mar in January, but Benfica remained undisturbed and with 23 consecutive wins, they won their 20th league title on 11 March. They were finally stopped by Porto in Estádio das Antas on 1 April, but still a European record for most consecutive domestic wins with 29, dating back to April 1972. A week later, they also lost their domestic invincibility when Leixões defeated them for the Portuguese Cup, ending over one-year of undefeated streak. In final part of the season, Benfica drew again with Atlético but remained undefeated winning 28 games in 30, setting a record for longest distance for second place with 18 points. Eusébio with 40 goals was the European Golden Shoe for his second time.
