Charles Wesley Thomas (born December 26, 1978) is an American former left fielder in Major League Baseball.

He steadily improved while splitting time between two teams in 2003, hitting .324 in 47 games after being called up to Double-A Greenville.

That season, he got a chance to play at Triple-A Richmond when Atlanta called up or released the outfielders ahead of him.

He went 31-for-79 (.379) in June, led the International League in hitting and on-base percentage, and was selected to the All-Star team.

At the 2004 Winter Meetings, the Braves traded Thomas and pitchers Juan Cruz and Dan Meyer to the Oakland Athletics for Tim Hudson.
