Hoopeston is a city in Grant Township, Vermilion County, Illinois, United States. It is part of the Danville, Illinois, Metropolitan Statistical Area. The population was 5,965 at the 2000 census, and 5,602 in 2009.
Hoopeston was laid out in 1871. It was named for Thomas Hoopes, one of the men who offered land for the crossing of two railroads: the Lafayette, Bloomington and Western Railroad and the Chicago, Danville and Vincennes Railroad. The two railroads separated the town into four sections. The latter railroad still exists and is now operated jointly by CSX Transportation and Union Pacific Railroad.
In 1890, Greer College was established in Hoopeston, funded by a gift of $40,000 and 500 acres (2.0 km2) of land from John Greer.
