The Silver Bear for Best Actor was an award presented at the Berlin International Film Festival from 1956 to 2020. It was given to an actor who has delivered an outstanding performance and was chosen by the International Jury from the films in the Competition slate at the festival. Beginning with the 71st Berlin International Film Festival, the award was replaced with two gender-neutral categories: the Silver Bear for Best Leading Performance and the Silver Bear for Best Supporting Performance.
