In Lost, what was Sawyer’s birth name?

In Lost, Sawyer’s birth name was James Ford.

He adopted the nickname “Sawyer” after his parents’ deaths, using the con man’s name connected to the tragedy that shaped his childhood. As an adult, he became a skilled confidence trickster and eventually used several aliases during his criminal schemes.

The name James Ford is distinct from Sawyer, the alias most characters use throughout the series. The con man himself is identified as Anthony Cooper, who also later uses the name Tom Sawyer. That connection explains why Sawyer chose the nickname, but James Ford remains his real name.

Sawyer’s identity is gradually explored through flashbacks, which reveal his family history, his pursuit of Cooper, and the emotional reason behind his deception. On the island, his relationships with Kate, Juliet, and the other survivors gradually make him less isolated and more cooperative.
