100m: 10.00 s (Eugene 2008) 200m: 19.63 s (Lausanne 2006) Xavier Carter (born December 8, 1985) is an American retired professional track and field athlete.

After his high school career, Carter played in the 2004 U.S. Army All-American Bowl and was named to USA Today's All-USA team.

[7] On July 11, 2006, at the Grand Prix in Lausanne, Switzerland, Carter ran what was then the second fastest 200 m race ever, recording a time of 19.63 s. As of October 2023, that time makes him the eleventh fastest man in the history of the 200-metre dash after Usain Bolt, Yohan Blake, Michael Johnson, Erriyon Knighton, Noah Lyles, Walter Dix, Letsile Tebogo, Justin Gatlin, Tyson Gay, and Andre de Grasse.

[10] Competing in his first 400 m race of the season, Carter posted a time of 44.70 s at the Reebok Grand Prix, breaking Kerron Clement's track record by one hundredth of a second.

Police stopped the sprinter in Gainesville, FL as they judged him to be playing his car stereo too loudly and upon approaching his vehicle they allegedly saw a concealed, loaded handgun.

[10] Carter, along with former New England Patriot Jermaine Cunningham and former Gator Jonathan Demps, was arrested in 2007 after an altercation with a Jimmy John's employee.

The group became "verbally abusive, struck the employee with empty soda cans and a sandwich, and fled the store" after the clerk asked them to pay for a bag of chips.
