The 'Fast & The Furious' star, 40, whose remains were cremated on Thursday, was interred at the iconic Hollywood cemetery, reported Radar online.
The ceremony took place at the Court Of Liberty, one of the cemetery's historical sites.
An American flag was allegedly folded in a triangle and displayed during the ceremony, and then given to the star's family.
More than three dozen people dressed in black and grey arrived at the landmark cemetery, where Walker's framed portrait has been set on an easel.
