The 2011 Deutsche Tourenwagen Masters season was a multi-event motor racing series largely based in Germany for highly modified touring car racing cars and is one of the most popular sedan car-based motor racing series in the world. The series features professional racing teams and drivers and is heavily supported by car manufacturers Audi and Mercedes-Benz. Each race features 18 V8-powered racing cars built according to the technical regulations of the Deutsche Tourenwagen Masters. It was the twenty-fifth season of premier German touring car championship and also twelfth season under the moniker of Deutsche Tourenwagen Masters since the series' resumption in 2000. It was the final season running the 4-door saloon-style spec cars, which has been the series' sole car style requirements since 2005 (although 4-door saloon-style spec cars were introduced majorly in 2004 but few coupé cars were also featured due to cost reasons). It was also the final season that all DTM cars ran with the sequential manual gearbox shifters before all DTM cars switched to sequential semi-automatic paddle-shifters for the following season.

Canadian Mercedes-Benz driver Bruno Spengler led the series after five races. After winning the season-opening Hockenheim and the most recent race at the Norisring, Spengler held a three-point lead over German Audi driver Martin Tomczyk who won races at the Red Bull Ring and Lausitzring. The two held a points gap over third-placed Audi driver Timo Scheider. The other race winner was Audi driver Mike Rockenfeller, although after his Le Mans sportscar accident Rockenfeller had to take a break from DTM to recover with series veteran Tom Kristensen replacing him.
