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.

Founded in 1834, it was situated on Chicago Rd, a mail route that ran from Chicago to the far West. There were dozens of small cabins along Somonauk Creek; wmong them was an Underground Railroad stop. Many of the people of Somonauk died due to lack of food and poverty.

Somonauk Creek is a tributary of the Fox River, which it joins in the Northville Township part of Sheridan, Illinois, United States. Somonauk Creek is approximately 36 miles (58 km) in length, and its source is 3.5 mi (6 km) north of Waterman. It has been dammed to form Lake Holiday, south of the village of Somonauk. The lake is the second lake in the City of Sandwich, with the first, Lake Davis, having been drained in the early 1900s to create usable farmland. The community later needed a lake to replace the one it lost, so in agreement with the Village of Somonauk, the community decided to place a dam on Somonauk Creek to form the new lake. The lake was marketed to the suburbs of Chicago as a recreation spot, with the community later making it a permanent subdivision, with housing located around the whole lake.
