Wes Chatham (born 11 October 1978) is an American actor best known for his roles as Amos Burton in the science fiction series The Expanse (2015–2022) and Castor in The Hunger Games film series (2014-2015). Chatham was born in Atlanta and grew up in North Georgia.

Wes's parents divorced when he was two and he spent most of his childhood with his mother, sister, and brother. On a whim, Wes's mother took his sister to a audition for a Tide commercial in Savannah, Georgia and brought him along. While waiting for his sister in the lobby, the casting director discovered Wes and, at the age of seven, he received his first acting job for Tide.
