Saw Gerrera is a fictional character in the Star Wars franchise. He first was introduced in a 2012 episode of the animated series The Clone Wars, in which he is voiced by Andrew Kishino. Hailing from the planet Onderon alongside his sister, Steela, they are introduced as Onderon loyalists working to free the planet from the rule of an illegitimate king backed by the Confederacy of Independent Systems and are mentored in military combat by the Jedi and clone troopers. While they are able to free their planet, his sister is tragically killed in action. An older version of the character appears in the live-action film Rogue One (2016), played by Forest Whitaker. He is depicted as a key rebel leader who is expelled from the Rebel Alliance due to his extreme methods, but he remains instrumental in uncovering the Death Star's existence and inspiring his protege and foster daughter, Jyn Erso, to help the Alliance.

Saw's character makes recurring appearances throughout Star Wars media; Whitaker voices Saw in the animated series Star Wars Rebels, the video game Star Wars Jedi: Fallen Order, and appears in the live-action television series, Andor (2022–2025). Saw also appears in The Bad Batch, with Kishino reprising his role. Many of his appearances depict him as an effective soldier whose methods become extreme. Other appearances explore Gerrera's battles against the Empire and the toll they take on him mentally, as well as his relationship with the Alliance, and his work uncovering the Death Star.

The character has received positive reception from critics for representing the darker aspects of the Rebel Alliance, and Whitaker's performance in both Rogue One and Andor, with the latter earning him an Outstanding Guest Actor in a Drama Series nomination at the 77th Primetime Emmy Awards.

Though Saw appears as an animated character in The Clone Wars, that was not the original plan for him. On the Star Wars show, Pablo Hidalgo of Lucasfilm's Story Group revealed the character's origin: "He started off before that. George Lucas had him in mind for his live-action TV series that was in development, which ultimately never happened, but he found a place to put Saw into a story in Clone Wars."

Supervising director of The Clone Wars Dave Filoni stated: "We wanted a brother/sister duo on Onderon, and the character Saw was a character that George had already created, and he just wanted to involve and tell a little more about that character. So in the course of that we created Steela [to be Saw's sister], who would act as a natural foil to Ahsoka."

Andrew Kishino, who voices Saw in The Clone Wars, said that the character "Has even sort of, embodied in him, that feisty spirit of the Rebellion. The take-no-garbage kind of individual. He's stoic and strong and brash. He's 'that' guy, and it's that kind of strength tempered with Steela's calm, level-headed thinking, that is, to stand up to something that will ultimately become the Empire, absolutely critical and necessary.

Saw Gerrera's name is a "mnemonic riff" on the name of the Argentinian communist Che Guevara. Gerrera is also a heterograph of the Spanish word "guerrera", meaning "female warrior", describing Steela.^{[citation needed]}

Entertainment Weekly revealed the character's appearance in Rogue One on June 22, 2016. The film's director, Gareth Edwards, had wanted a character to showcase the more "militant" and "extreme" side of the rebellion. Co-producer Kiri Hart suggested using Gerrera, a pre-established character, in this role. Gerrera appears significantly older in Rogue One than he did in The Clone Wars, despite the two works taking place only roughly twenty years apart.
