Cedar Lake is a town in Hanover and Center townships, Lake County, Indiana, United States. It is near the Illinois state line. Its population was 11,560 at the 2010 census. The town is notable for its location on Cedar Lake, the Lake of the Red Cedars museum, and veteran charity organization Operation Combat Bikesaver.
Cedar Lake was settled by pioneers in the mid-19th century and was originally named West Point; the name “Cedar Lake” belonged to a nearby town that is now called Creston, Indiana. In 1839, the town that was then called West Point competed with the settlements of Liverpool and Lake Court House (later called Crown Point) to be the county seat of Lake County, but lost out to Liverpool. By 1870, the Cedar Lake Post Office was established, giving the area a new name. After the Monon Railroad came to the lake's western shore in 1882, many new residents flocked to the area along with tourists who saw the lake as a resort destination. From the late 19th century to the early 20th century, Cedar Lake was a popular place for Chicagoans looking for a retreat from the city. The lake had over 50 hotels at the time and several pavilions and ballrooms that brought many well-known bands to entertain the visitors.
The Lassen Hotel and Monon Park Dancing Pavilion are listed in the National Register of Historic Places.
According to the 2010 census, Cedar Lake has a total area of 9.61 square miles (24.89 km2), of which 8.22 square miles (21.29 km2) (or 85.54%) is land and 1.39 square miles (3.60 km2) (or 14.46%) is water.
