The Chicago Sky are an American professional basketball team based in Chicago, playing in the Eastern Conference of the Women's National Basketball Association (WNBA). The franchise was founded before the 2006 WNBA season began. It is owned by Michael J. Alter (principal owner) and Margaret Stender (minority owner). The team experienced a period of success from 2013 to 2016, making four playoff appearances and playing in the 2014 WNBA Finals.

Unlike many other WNBA teams, the Sky is not affiliated with a National Basketball Association (NBA) counterpart, although the Chicago Bulls play in the same market.
