The 2013 Chicago Sky season was the franchise's 8th season in the Women's National Basketball Association, and their third season under head coach Pokey Chatman.
With the addition of Elena Delle Donne, expectations were high for the Sky to finally reach the playoffs. Delle Donne, along with Sylvia Fowles, Epiphanny Prince, Courtney Vandersloot, and Swin Cash finished the regular season with the best record in the Eastern Conference - thus giving the Sky, their first regular season Conference title and the first seed in the 2013 WNBA Playoffs. The Sky were ultimately swept in the Conference Semifinals by the Indiana Fever.
