List of Saw (franchise) cast members

The list of Saw cast members is a list of actors who voiced or portrayed characters appearing in the Saw franchise created by James Wan and Leigh Whannell. Tobin Bell (Jigsaw) is the only actor to make appearances in all eight films, throughout which he is complemented on screen by actors ranging from well-known ones such as Danny Glover, Cary Elwes, and Donnie Wahlberg to lesser-known actors such as Dina Meyer and Lyriq Bent, among others. While many actors reprise their roles for cameos and minor appearances, the only actors besides Bell and Shawnee Smith to appear with major roles in more than three films were Costas Mandylor (Mark Hoffman) and Betsy Russell (Jill Tuck), both of whom appear in the latter five installments of the series.

In other Saw media, a significant number of actors have either been replaced or omitted from appearing. In the video game, Tobin Bell was the only actor to reprise his role from the films. Other characters such as Amanda Young, Obi Tate, and Jeff Ridenhour all returned but were voiced by other actors. Other characters, including Pamela Jenkins and Steven Sing were mentioned but did not make any appearance. For the Saw roller coaster, Billy the Puppet was the only character to appear, with no voice provided for him. The lack of characters present is attributed to the physical restraints of actors in a roller coaster. A prequel comic book, Saw: Rebirth, featured many recurring characters but little actor corresponding or likeness' due to the comic not being supported by Twisted Pictures. Other actors likenesses were used in place of the films' actors.

While the films have not replaced any actors, their scripts have been altered to omit certain characters due to a number of conflicts. Cary Elwes' character, Dr. Lawrence Gordon, did not appear in subsequent films after Saw due to a lawsuit from payment issues for Elwes, although his character has been referenced many times since. Elwes reprised his character in the seventh film, Saw 3D.
