The Connecticut Sun are an American professional basketball team based in Uncasville, Connecticut that competes in the Eastern Conference of the Women's National Basketball Association (WNBA). Along with the Minnesota Lynx, the club was established in 1999 as part of the league's expansion from ten to twelve teams. The Miracle, the club's previous moniker, originated that year in Orlando, Florida, as the sister team to the NBA's Orlando Magic. Financial strains left the Miracle teetering on the brink of disbanding before the Mohegan Indian tribe purchased and relocated the team to Mohegan Sun, becoming the first Native American tribe to own a professional sports franchise. The derivative of the club's name comes from its affiliation with Mohegan Sun, while the team's logo is reflective of a modern interpretation of an ancient Mohegan symbol.

Capitalizing on the popularity of women's basketball in the state, as a result of the success of the UConn Huskies, the Sun also held the distinction of being the only WNBA franchise not to share its market with an NBA team from 2003 until the Seattle SuperSonics relocated, leaving the Storm as an independent team in Seattle.

The Sun have qualified for the WNBA Playoffs in twelve of their eighteen seasons in Connecticut.
