Terry O’Quinn portrays John Locke in the television series Lost.
Locke is one of the survivors of Oceanic Flight 815 and quickly develops a powerful connection to the island. Before the crash, he used a wheelchair; after landing, he discovers that he can walk, making his recovery one of the series’ earliest major mysteries.
The character is named after the English philosopher John Locke, and the show repeatedly links him to questions about faith, destiny, and the meaning of the island. His ideological clashes with Jack Shephard become one of Lost’s most important continuing conflicts.
Terry O’Quinn’s performance earned major recognition, including the Primetime Emmy Award for Outstanding Supporting Actor in a Drama Series in 2007. The actor is sometimes confused with Michael Emerson, who played Benjamin Linus, another major character associated with the island’s mythology.
