The 1973–74 Phoenix Suns season was the sixth for the Phoenix Suns of the National Basketball Association. It was the first of 14 seasons head coach John MacLeod spent with Phoenix. The season would also be the last for former All-Star forward/center Connie Hawkins, traded to the Los Angeles Lakers after appearing in nine games for the Suns. Charlie Scott would repeat as an All-Star, but who missed 30 games due to injury despite his NBA career-high 25.4 points a game. The team went on to finish the season 30–52, a career-worst for MacLeod and the franchise's poorest record since their inaugural season.

Dick Van Arsdale averaged 17.8 points on the season, while Neal Walk averaged 16.8 points and a team-high 10.2 rebounds per contest. Keith Erickson, obtained by the Suns along with a future second round pick in the Hawkins trade, enjoyed a career-high 14.6 points a game in his ninth year in the NBA and first with Phoenix.

Van Arsdale was named to the NBA All-Defensive Second Team, while Mike Bantom, a rookie out of Saint Joseph's, was named to the All-Rookie Team.
