Lieutenant Mark Hoffman is a fictional character in the Saw film series. He is portrayed by Costas Mandylor. While his character began as a legitimate police officer in Saw III, Hoffman went on to have a major role in the Saw films as Jigsaw's apprentice.

Saw III briefly showed Hoffman during the investigation of Troy's chain trap. Hoffman was shown to be listening in on Lieutenant Rigg's conversation with Kerry about Jigsaw's ability to continue his work. Hoffman simply grabbed one of the chains from the traps' aftermath and commented as to why the door had to be cut open by the police to secure the crime scene. He was very apathetic and glib while speaking to Rigg and Kerry. Rigg showed that this bothered him.

During Saw IV, Hoffman is called to the police morgue to hear a cassette tape that is found in Jigsaw's stomach during his autopsy. It is later discovered that the events of Saw III and Saw IV occurred at the same time, so this scene actually happened at the end of Saw IV.
