The Livestrong Foundation is a United States nonprofit organization that provides support for people affected by cancer. The foundation, based in Austin, Texas, was established in 1997 by cancer survivor and former professional road racing cyclist Lance Armstrong, as the Lance Armstrong Foundation. The Livestrong brand was launched by the foundation in 2003. Armstrong resigned from the foundation in 2012 after his admission of doping, leading to the rebranding of the entire organization as Livestrong Foundation.
