The 2011 FIA GT1 San Luis round was an auto racing event held at the Potrero de los Funes Circuit, San Luis, Argentina on 4–6 November, and was the final round of the 2011 FIA GT1 World Championship season. It was the FIA GT1 World Championship's second race held in Argentina, a week after the 2010 San Luis round at the 6.270 km (3.896 mi) circuit. This event was supported by the TC 2000 Championship, Fiat Linea Competizione and the Argentine Formula Renault Championship.
Michael Krumm and Lucas Luhr went into this weekend as championship leaders in the Drivers Championship, eleven points ahead of Young Driver AMR drivers Darren Turner and Stefan Mücke. The Championship was up for grabs, as far down as sixth place Marc VDS driver Maxime Martin who was on 98 points and could have won the championship by winning the two races thus picking up 33 points and tying with Krumm and Luhr but only if the Germans either did not finish in the points or retired. Martin could winn the championship by picking up a possible six wins to Krumm and Luhr's four. In the Teams Championship, Young Driver AMR overtook JRM in the previous round at Beijing and led by eight points.
Markus Palttala replaced Yann Clairay for this round returning behind the wheel of the No. 10 Belgian Racing Ford GT after racing with the team at Silverstone. Clairay replaced Bertrand Baguette behind the wheel of the No. 41 Marc VDS car. Exim Bank Team China drafted in two new drivers Yelmer Buurman and Francesco Pastorelli for the Argentine round both making their FIA GT1 débuts replacing Ho-Pin Tung and Jeroen den Boer. Ricardo Risatti returned to the championship competing in the No. 40 Marc VDS Ford replacing Marc Hennerici. He made a cameo appearance in the San Luis round last season with Young Driver AMR. Christopher Haase also returns to the championship replacing Benjamin Leuenberger in the No. 47 DKR Lamborghini. The 2010 FIA GT3 champion raced for Reiter Engineering in the previous season.
