The 1981–82 season was Sport Lisboa e Benfica's 78th season in existence and the club's 48th consecutive season in the top flight of Portuguese football, covering the period from 1 July 1981 to 30 June 1982. Benfica competed domestically in the Primeira Divisão, Taça de Portugal and the Supertaça Cândido de Oliveira, and participated in the European Cup after winning the previous league.

In Baróti's second season, Benfica invests heavily to strengthened their choices of forwards, signing Fernando Folha from Boavista, plus the Yugoslavian Zoran Filipovic from abroad. However, the league campaign is disappointing, with Benfica losing three times before November. In other competitions, Benfica loses to 4–1 to Bayern Munich in the European Cup; the same result that Porto defeated them in the Supertaça. In the second half of the season, Benfica kept chasing Sporting in the title race, with the distance fluctuating several times, the shortest at three points, the longest at seven. In April, Benfica is knocked-out of the Portuguese Cup and a month later, loses the title to Sporting.

Benfica started the new season as reigning champions, after Lajos Baróti led the team to their first league title in three years. Before President José Ferreira Queimado left his job, he signed an one-year extension with Baróti, something that new President Fernando Martins did not agree, claiming it left him with his hands tied.Toni became his assistant manager. In the pre-season, Benfica lost the aforementioned Toni to retirement, but invested heavily into forwards. To sign Fernando Folha from Boavista, Benfica had to outspent Porto and add Jorge Silva to the transfer. They also signed Yugoslavian striker Zoran Filipovic from Club Brugge. Other strikers approached but not signed were Pier Tol,Fernando Gomes,Sarr Boubacar, and Peter Houtman. The pre-season began on 28 July with medical tests and the presentation game with Boavista occurred on 4 August. Afterwards, Benfica competed in the inaugural Lisbon International Tournament and had a short tour for North America, competing in the Toronto Tournament.
