The website for the charity indicated there was an event in Southern California on Saturday to benefit victims of Typhoon Haiyan in the Philippines.
Along with Vin Diesel, the 40-year-old Walker has been one of the stalwarts of the "Fast and Furious" movie series, characterized by its racing scenes and attractive cast.
The box-office success of the first film in 2001 fueled sequels. The series' sixth installment came out earlier this year, topping the Memorial Day weekend box office.
A seventh film is scheduled for release in 2014.
On his verified Twitter account, Walker described himself as "outdoorsman, ocean addict, adrenaline junkie ... and I do some acting on the side."
Walker also is the star of "Hours," an independent film scheduled to be released December 13 about a father struggling to keep his newborn infant alive in the aftermath of Hurricane Katrina in New Orleans.
