The 1985 Brazilian Grand Prix was a Formula One motor race held at Jacarepaguá in Jacarepaguá, Rio de Janeiro on 7 April 1985. It was the first round of the 1985 Formula One World Championship.

In qualifying, Ferrari driver, Michele Alboreto took pole, his second of his career. In the race, he would finish second on the podium behind eventual race winner, Alain Prost, while Elio de Angelis rounded out the podium in the Lotus car. Of note, even though René Arnoux finished 4th for Ferrari, he was sacked after the race, with both the team and Arnoux never revealing the reason behind the sacking. The driver who finished 7th in this race, Stefan Johansson, was picked up by the Scuderia for the rest of the year.
