Damion Marquez Williams James (born October 7, 1987) is an American former professional basketball player who last played for Vaqueros de Bayamón of the Baloncesto Superior Nacional (BSN).

[1] He initially signed to play college basketball at the University of Oklahoma for head coach Kelvin Sampson.

When Sampson took the head coaching position at Indiana University, the administration at Oklahoma released James from his letter of intent and he switched his decision to Texas.

James started all 35 games, along with fellow freshmen Kevin Durant and D. J. Augustin, in leading the Longhorns to a 25–10 record.

[2] James averaged 13.2 points and 10.3 rebounds,[2] helping Texas win a share of the Big 12 regular season title.

While talking about the Texas Longhorns on Selection Sunday, Dick Vitale said that James may be the most athletic player in all of college basketball.

James, along with A. J. Abrams and Justin Mason, started all 35 games for the Texas Longhorns that went 23–12 and advanced to the second round of the 2009 NCAA Men's Division I Basketball Tournament.

[2] On April 15, 2009, James entered his name into the 2009 NBA draft, without hiring an agent, and thus retaining his NCAA eligibility.

[18] On August 4, 2015, James signed a one-year deal with Le Mans Sarthe Basket of the LNB Pro A.

James' tenure with the Kings was considered sub-par, as he helped the team win just one game and from the field, he shot a mere 22%.

[24] On November 4, 2017, James signed with the Israeli team Hapoel Eilat for the 2017–18 season, joining his former teammate Mike Rosario.
