The 2006–07 Miami Heat season was the 19th season for the franchise in the National Basketball Association (NBA). The Heat, for the first time in franchise history, entered the season as the defending NBA champions, having defeated the Dallas Mavericks in the 2006 NBA Finals in six games. On January 3, 2007, head coach Pat Riley took a leave of absence citing hip and knee problems and was replaced by Ron Rothstein.

The Heat ended the season with a four-game playoff loss in a sweep to the Chicago Bulls in the first round and the Heat became the first defending NBA champions
