On July 9, 2015, Chandler signed a four-year, $52 million contract with the Phoenix Suns. On November 27, he suffered a strained right hamstring against the Golden State Warriors. He subsequently missed eight games. On January 21, Chandler grabbed a season-high 20 rebounds in a 117–89 loss to the San Antonio Spurs. Two days later, in a 98–95 win over the Atlanta Hawks, Chandler tied a Suns record with 27 rebounds, including 17 in the first half, and also had 13 points and a season-high five assists. His 27 rebounds equaled the record total set by Paul Silas in 1971, and his 13 offensive boards set a franchise record. Chandler also became the first Suns player in franchise history to record consecutive 20-rebound games.
