Parker and her family moved to Naperville, Illinois at the age of two, where she spent her childhood. Her family loved basketball and she began playing at an early age. Her father played basketball at the University of Iowa in the 1970s. The Parker family were also huge Chicago Bulls fans. Candace was worried about playing basketball, fearing she would not live up to the level of play her father and brother demonstrated, so she focused on playing soccer. It wasn't until the eighth grade that her family convinced her to play basketball. Her father helped coach and critique her. Parker said of the experience, "He did things to make me mad, to challenge me, because I was so much more athletic and had so much more knowledge of the game than everyone else that sometimes I just coasted. If me and my dad went to a park and he didn't think I was practicing hard enough, he'd just get in the car and leave. And I'd have to run home. I mean run home. Once I figured that out, I'd always try to go to close-by-parks. "
