Lake Holiday is a census-designated place located on Lake Holiday in Northville Township, LaSalle County, Illinois, United States. Its population was 5,687 as of the 2020 census.

The homes on the western banks of the lake are served by the Somonauk Fire Department/EMS and the Somonauk School District, while the eastern banks of the lake are covered by Sandwich municipal services (Fire/EMS, CUSD 430). However, due to the community's location south of the LaSalle-DeKalb county line, neither Sandwich Police nor Somonauk Police have any jurisdiction. Instead, the area is patrolled by local security, which has limited authority. For serious matters, the community is covered by the LaSalle County Sheriff's Department, which has a substation in the Northville Township Building, a few miles to the south of Lake Holiday.

The Lake Holiday CDP includes the neighborhoods surrounding Lake Holiday as well as neighboring Wildwood, which sits to the east of County Highway 3. Lake Holiday was created in the mid-1960s as a lake resort community, with its property owners association being incorporated on July 2, 1965. Wildwood was created around the same time, as a modular home community just across the highway. Starting in the early 1990s, an annex to Wildwood known as "Wildwood South" or "New Wildwood" was created, with completion around 2002. Both subdivisions share a gas station and a small retail area, with a restaurant having been built in 2006-2007 farther north, just south of the county line.

Lake Holiday was created by damming up Somonauk Creek in 1965, on its path south toward its confluence with the Fox River just north of Sheridan.
