Terrence Deshon Williams (born June 28, 1987) is an American former professional basketball player.

At Rainier Beach High School, Williams was a four-year starter on the basketball team.

[6] Williams had extraordinary overall athletic abilities as recognized by his college coach Rick Pitino.

[9] He saw playing time early in his rookie season but was relegated to a lesser role as a result of poor behavior; he was late for meetings, missed a team bus and slept in through a shoot-around.

[10] His playing time increased after an injury to Devin Harris and a meeting with the team president, Rod Thorn, and interim coach, Kiki VanDeWeghe.

[10] On April 9, 2010, Williams recorded a triple-double with a career-high 27 points, 13 rebounds and 10 assists in a double overtime 127–116 win over the Chicago Bulls.

[12] Fines issued by the Nets failed to deter Williams from his past transgressions of being late to practices and team meetings.

[13] Nets head coach Avery Johnson denied that the assignment was due to disciplinary reasons but instead because the team did not have enough minutes for Williams.

[17] In a 2014 interview, Daryl Morey called the loss of a first-round pick for Williams one of his worst moves as a general manager.

[30] He set the D-Fenders franchise single-game scoring record with 50 points on January 31, 2014, against the Idaho Stampede, surpassing 49 earlier that season by Manny Harris.

[41] In April 2015, Williams signed with Guaiqueríes de Margarita of Venezuela for the rest of the 2015 LPB season.

On October 7, 2021, the U.S. Attorney for the Southern District of New York, Audrey Strauss, criminally charged Williams and 15 others in connection with an alleged scheme to defraud the NBA's health plan, in which nearly $4 million in fraudulent claims appeared to have been made.

The charges alleged that Williams obtained fraudulent medical and dental invoices, sent them to his co-conspirators, including other former NBA players, and claims were submitted by the aforementioned co-conspirators to the plan, which paid "most" claims for medical care never rendered.
