Wasco is an unincorporated suburb of Chicago in Kane County, Illinois, United States. It has a post office (60183), a few restaurants, and an elementary school sharing its namesake "Wasco Elementary School". Wasco is located along Illinois Route 64 approximately 4 miles west of St. Charles and is partly contained within the village of Campton Hills. The area outside the downtown section is mostly residential homes, spanning several blocks. Although it has a large population (estimated to be over 5,000), Wasco has never been incorporated as its own entity. Only two other Chicago suburbs are like this. Medinah and La Grange Highlands, both have populations well over 1,000, and have still remained unincorporated.
Wasco was originally named Compton, after an early family that settled the area. The Wasco Post Office was originally built in 1836 by a lay preacher named Dr. King on King's Mill Road near Lake Campton. The post office was then moved to its present location on Illinois Route 64 in 1890. Throughout the years, the building has undergone multiple renovations and has served many different functions, including a milk depot, a general store, an antique store, and a repair shop. Other historic buildings in Wasco include the Campton Town Hall built in 1873, the Wasco Baptist Church built in 1891, and Wasco Elementary built in 1906
