The 1999–2000 NBA season was the 32nd season for the National Basketball Association's Phoenix Suns. During the offseason, the Suns acquired All-Star guard Anfernee Hardaway from the Orlando Magic, while signing free agent Rodney Rogers and re-signing former Suns center Oliver Miller. Scott Skiles would come on as head coach, replacing Danny Ainge after a 13–7 start to the season. The Suns would finish third in the Pacific Division at 53–29, and extend the franchise's record for playoff appearances before losing in the Western Conference semifinals.

Clifford Robinson led the team in scoring at 18.5 points per game. Hardaway, Jason Kidd, Rodney Rogers, Tom Gugliotta, and top draft pick Shawn Marion rounded out a list of six Suns players averaging double-digits in points. Kidd led the NBA in assists per game and was tied for fifth in steals, while being selected for the 2000 NBA All-Star Game. Rogers finished the regular season fourth in three-point field goal percentage, and won the NBA Sixth Man of the Year Award. Kidd would earn All-NBA First Team and NBA All-Defensive Second Team honors. In March, former Suns guard Kevin Johnson came out of his retirement and played in six games. He would then retire for the second time after the playoffs.
