Germantown Hills is a village in Woodford County, Illinois, approximately 8 miles (13 km) northeast of Peoria.

A steam sawmill was built in 1860, and in the 1890s, the Union House was erected as a tavern, grocery store, and saloon.

[3] The area remained almost completely agricultural until the incorporation of Oak Grove Park in 1954.

In 1967, the name Oak Grove Park was dropped in favor of Germantown Hills.

The village's population would rise steadily until the 1980 census, when the annexation of the Whispering Oaks subdivision brought the number to 524.

[3] Rampant development, fueled by suburbanization in the Peoria Metropolitan Area, brought the population to its most-recent count of 3,438.

[5] Illinois State Route 116, a four-lane divided highway, runs through the center of the village and connects it to Peoria, serving as the focal point for development and residences.
