Tarso Anibal Santanna Marques (born 19 January 1976) is a Brazilian racing driver. He previously participated in 24 Formula One Grands Prix, all driving for the Minardi team, but scored no championship points in three separate seasons and never completed a full year in the sport. Racing career Open wheel racing After five years of karting, Marques raced in Formula Chevrolet in his home country aged only 16, and he won the title at his first attempt. In 1993 he moved up to Formula Three Sudamericana and subsequently European Formula 3000, and became the youngest driver to win races at both levels.

Marques welcomed the driver change as the extra finance would enable the team to progress, adding, "Yoong brought the sponsor for the team already two or three races ago so he should be in the car." His two ninth-place finishes remained Minardi's best results of the season, but he was nearly always outpaced by Alonso.
