Westfield Southgate, formerly Southgate Plaza and South Gate Shopping Plaza, is a shopping mall in Sarasota, Florida. Opened in 1956, it is anchored by Dillard's and Macy's.
Southgate Plaza opened in 1956 as a strip mall. It was enclosed in 1988. The original strip included two supermarkets: Publix and Winn Dixie's Kwik Chek, along with a W. T. Grant and Woolworth. J. C. Penney was added as part of a 1961 expansion.
W. T. Grant closed its store in 1976, which was then sold to Burdines. A J. W. Robinson's department store replaced the former J. C. Penney in 1978, after J. C. Penney moved to Sarasota Square Mall (now Westfield Sarasota Square). Robinson's became Maison Blanche in 1987 and Dillard's in 1992. Three years after Robinson's opened, an enclosed wing was added.
In 1994, Publix moved to a larger store across the street. The Publix building became Saks Fifth Avenue in 1996.
Following the opening of Saks, the mall was renovated to include more upscale stores such as Williams-Sonoma, Ann Taylor, and Banana Republic.
Westfield Group bought the mall in 2002, renaming it Westfield Southgate. Burdines became Macy's in 2003.
In 2012, Saks confirmed that it would move to Mall at University Town Center, a new mall being built in Sarasota by Taubman Centers. The Saks closed in October 2014 with the opening of that store. The Dillard's store reduced the hours it was open.  In addition, Westfield announced plans to add a lifestyle center element to the mall.
