Alexander B. Witt (born 1952) is a Chilean Hollywood cinematographer, working mainly as a cinematographer and second-unit director. His feature-film directorial debut came in 2004 with the film "Resident Evil: Apocalypse," based on the popular Capcom video game series. Witt also served as second-unit director on the James Bond film "Casino Royale" in 2006.

In a 2004 interview for IGN, he tells his story: "I was born in Chile, a third-generation German there. Then we moved to Mexico, and from Mexico in '73 I moved to Europe, where I started working in film. I started with Arriflex, the company that makes cameras. I was there for a year, and it was a kind of internship year, where I worked in the sound department, in the lab, in the studio with real productions, and also assembled cameras. Then I moved to Europe, where I lived for three years, and then, in '76, I shot my first film as an assistant cameraman — it was '21 Hours at Munich.' And then I kept moving up: I became a focus puller, or first assistant cameraman, then a cameraman, and then a director of photography. Then I shot commercials as a director of photography, and in the late '80s and early '90s I began directing commercials. I worked with Jan and shot his second unit as director of photography while he was the director of photography. It was he who gave me the chance on 'Speed 1' to start directing second unit."
