Ricardo Héctor Zunino (born 13 April 1949 in San Juan) is a former racing driver from Argentina who participated in Formula One from 1979 to 1981. He competed in 11 World Championship races and two non-Championship Formula One races, the 1980 Spanish Grand Prix and 1981 South African Grand Prix. At the 1979 Canadian Grand Prix, he replaced Niki Lauda at Brabham after the Austrian abruptly quit the team and Formula One. Zunino, attending the race as a spectator on a weekend off from his regular British F1 Championship drive, was chosen to take over the seat, having recently tested for the team.
