The 1985 Giro d'Italia was the 68th running of the Giro. It started in Palermo, on 16 May, with a 6.6 km (4.1 mi) prologue and concluded in Lucca, on 9 June, with a 48 km (29.8 mi) individual time trial. A total of 180 riders from twenty teams entered the 22-stage race, that was won by Frenchman Bernard Hinault of the La Vie Claire team. The second and third places were taken by Italian Francesco Moser and American Greg LeMond, respectively.

The Giro d'Italia is an annual multiple-stage bicycle race primarily held in Italy, while also starting in, or passing through, other countries. The first race was organized in 1909 to increase sales of the newspaper La Gazzetta dello Sport, and the race is still run by a subsidiary of that paper's owner. The race has been held annually since its first edition in 1909, except during the two world wars. As the Giro gained prominence and popularity the race was lengthened, and the peloton expanded from primarily Italian participation to riders from all over the world. The Giro is a UCI World Tour event, which means that the teams that compete in the race are mostly UCI WorldTeams, with some additional teams invited as 'wild cards'.
