2011 ATP Challenger Tour Finals

The 2011 ATP Challenger Tour Finals was a tennis tournament played at the Ginásio do Ibirapuera in São Paulo, Brazil, between November 16 and November 20, 2011. It was the first edition of the event. The tournament was run by the Association of Tennis Professionals (ATP) and was part of the 2011 ATP Challenger Tour. The event took place on indoor hard courts.
