The Terminator (also known as T-800 and T-850) is a fictional character from the Terminator franchise portrayed by both Arnold Schwarzenegger and numerous actor stand-ins digitally overlayed with Schwarzenegger's likeness. The Terminator itself is part of a series of machines created by Skynet for infiltration-based assassination missions, and while an android for its appearance resembling a human, it is described as a cybernetic organism for consisting of living tissue over a robotic endoskeleton.

The first appearance of the Terminator was as the titular antagonist in The Terminator, a 1984 film directed and co-written by James Cameron. While the original Terminator was destroyed, other androids using the same "mold" that made them look like Schwarzenegger — said physical template was described in-universe as the "Model 101" — are featured in the sequels. In Terminator 2: Judgment Day, Terminator 3: Rise of the Machines and Terminator Genisys, Schwarzenegger is the protagonist instead of the antagonist, pitted against other Terminators sent by Skynet. In Terminator Salvation, the T-800 appears briefly as a T-RIP (Resistance Infiltrator Prototype) CGI model and T-800. In the context of the stories, the plot device of having various robots looking the same provides a certain continuity for the human characters by exploiting their emotional familiarity with a particular "human" visage associated with each "model".
