Bay Park Square is a shopping mall owned by Simon Property Group, in the Green Bay, Wisconsin suburb of Ashwaubenon, in the United States. The mall opened in 1980 under the ownership of DeBartolo Corporation. Bay Park Square is located one mile (1.6 km) away from Lambeau Field on South Oneida Street (County Trunk Highway AAA).
The mall's anchor store is Kohl's. There are 3 vacant anchor stores that were once Shopko and 2 Younkers stores.
The mall also has an American football stadium-themed food court, known as the "Supper Bowl".
Montgomery Ward announced plans for a new $10 million store and 700,000 square feet (65,000 m2) adjacent shopping mall in the town of Ashwaubenon, Wisconsin in 1969, which would replace their downtown Green Bay store. The mall was originally intended to open in 1971. Montgomery Ward hired E.D. Pehrson Associates of Chicago as developer. After delays, the Montgomery Ward store opened in 1972.
After the project stalled again in the mid-1970s, the Edward J. DeBartolo Corp. was brought in by Montgomery Ward as the new developer. By this time, the mall project was increased to 786,000 square feet (73,000 m2). In 1979, Shopko was announced as the second anchor store of the new mall. Construction on the mall began in 1979, and the mall opened in 1980.
In 1981, the mall was expanded, adding an east wing and a Kohl's Department Store. The project added 94,000 square feet (8,700 m2) of space to the mall.
In 1995, the mall underwent a major renovation, remodeling much of the interior of the mall. A new west wing was added, which included a food court taking up the former Marcus Theatres space and a new 75,000 square feet (7,000 m2) Elder-Beerman department store as the fourth anchor, which replaced the mall's main entrance. The mall then added two new angled entrances, one that went through to the new food court, and another that went through to the mall walkway running parallel to the side of the new Elder-Beerman department store. Marcus Theatres built a new 16-screen move theater on an outlot of the mall. A 20,000 square feet (1,900 m2) addition was made to the Kohl's store at the same time.
Simon Property Group acquired Bay Park Square when they merged with the mall's owners, the DeBartolo Corporation.
Montgomery Ward closed in 2001. In 2003, the south wing was expanded and a new Younkers department store was built. Elder-Beerman closed in 2007 following their acquisition by Younkers' parent company, The Bon-Ton. A Younkers Furniture Gallery later replaced the Elder-Beerman store. Both stores closed in mid-2018 due to Bon-Ton's bankruptcy and the entire chain going out of business. Shopko would meet the same fate on June 16, 2019, when the last of its stores, including the Bay Park Square store, closed.
In 2019, a plan was announced to have Dave and Buster's occupy the former Younkers Furniture space. Panda Express, Blaze Pizza and Mission BBQ also announced plans to build in outlets on the mall property.
