The 1985–86 season was FC Dinamo București's 37th season in Divizia A. This was the season when it started the Lucescu era for Dinamo. Mircea Lucescu was brought as manager in the 14th round. He won his first trophy at the end of the season, the Romanian Cup, beating Steaua in the final, the team that just became European champions.
In the championship, Dinamo started badly, and continued that way, ending only fourth. The results were not good in the European competitions either. In the UEFA Cup, Dinamo was eliminated in the first round, by the Yugoslavian side Vardar Skopje.
In the game versus FC Bihor, in the 33rd round, the assistant manager Florin Cheran, was introduced in the team because of the medical problems in the squad. Cheran was 39 years old and ended his football career four years before.
