Six Flags Entertainment Village was a proposed 134-acre (54 ha) resort complex in Gurnee, Illinois, United States, across and west of Six Flags Great America, near Interstate 94. With its land owned by Six Flags, it was planned to be developed by Prism Development and was estimated to be US$400 million. It was expected to feature a water park, hotel, outdoor shopping mall, and theater.

This project was projected to generate over US$10,500,000 annually and attract 400,000 visitors each year. Construction was scheduled for multiple phases, with initial plans to open in 2000, and full completion of the project by 2002.

Opposition to Six Flags Entertainment Village arose in 1998 when towns and citizens criticized the project. A citizens group was formed titled "Citizens United for a Residential Village of Gurnee" (CURV), which opposed the resort due to concerns of overdevelopment, congestion, and rising tax prices. Plans for the complex stalled in 1999 after a majority of Gurnee residents voted against it on an advisory referendum.

In 1972, Marriott had purchased 600 acres (240 ha) of land around the Interstate 94 tollway, which was split by the tollway. The land to the east of Interstate 94 would be occupied by the Marriott's Great America (now Six Flags Great America) theme park, while the land to the west of Interstate 94 would be planned for a future hotel expansion. During construction of the theme park, the land to the west was occupied by early administrative offices and warehouses. Originally, an interchange was planned in 1973 by the Marriott Corporation on Interstate 94 for the planned expansion, but was rejected because the interchange could not lead into private property.

In May 1996, representatives from the Six Flags Great America amusement park met with officials from the village of Gurnee, Illinois, to obtain permission to build a new water park on a plot of land west of Six Flags Great America, across Interstate 94. The water park was planned to open in 1998 if approved. However, a spokesperson for the amusement park stated that plans were premature and might not proceed. Since the land that Six Flags wanted to use was not zoned accordingly, it would require a special-use permit.

Plans for a 136-acre (55 ha) resort complex were announced at a Gurnee board meeting on October 29, 1997. Titled Six Flags Entertainment Village, it would be on a separate plot of land west of Six Flags Great America, across Interstate 94, with the tollway dividing the two properties. It was described as "pedestrian-friendly," with small shops, a theme park, hotel, and an 8,000 to 12,000 seat multipurpose center included in the plans for the resort. The feasibility of the resort would be studied by a panel appointed by the then-mayor of Gurnee, Richard Welton. On October 30, 1997, the panel announced it would need more time to study and discuss the plans for the project, as they needed to develop recommendations on the project.

Gurnee officials later created an oversight committee on November 3, 1997, to keep the Gurnee village board updated on details after a trustee voiced concerns about the board being "out of the loop." This committee would operate independently from another committee that operates with the project's developer Prism Development. The Gurnee board postponed the appointment of the oversight committee a week after, on November 10, 1997, after the board had voted to invite Prism Development to make a presentation. Welton recommended that the board should be updated on the project's status before trustees were appointed for the oversight committee.

Prism Development proposed a four-way interchange near Washington Street, stating that it was "absolutely required" for the project "to become a reality." The interchange would divert traffic from the main entrance at Grand Avenue and would allow guests to instead get into both properties from either side. Part of the plan also included widening Washington Street into a four-lane road. Despite the proposition, consultants from Metro Transportation Group Inc. stated that the interchange would be necessary once later phases of the project began, with the estimation of phase one starting in 1999 and phase two starting in 2002. Additionally, the interchange would also require approval from the Illinois State Toll Highway Authority, Lake County, Illinois, and the village of Gurnee, but mayor Welton stated the interchange would create additional opportunities.
