The 2010–11 Phoenix Suns season was the 43rd season for the Phoenix Suns of the National Basketball Association (NBA). For the first time in eight seasons, the Suns will be without the play of power forward Amar'e Stoudemire, a 5-time All-Star and former Rookie of the Year who joined the New York Knicks in the summer. The Suns traded Jason Richardson on December 18, 2010 as part of a trade that brought Vince Carter to the Suns. On February 24, 2011, the Suns traded Goran Dragić and the draft pick they got earlier from Orlando in exchange for Aaron Brooks. Alvin Gentry was head coach and the Suns played their home games at US Airways Center.

Amar'e Stoudemire opted out of his final year of his contract and became an unrestricted free agent. He was to be paid $17.7 million. He later joined the New York Knicks.

Channing Frye re-signed with Phoenix on a 5-year, $30 million contract on July 1. One day later, the Suns signed power forward Hakim Warrick to a 4-year, $16 million contract. At the same time, Phoenix ended up trading Leandro Barbosa and Dwayne Jones to the Toronto Raptors in exchange for Hedo Türkoğlu.
