Jamaica Township is a township in Vermilion County, Illinois, USA. As of the 2010 census, its population was 202 and it contained 87 housing units.[2]
Jamaica Township was created from portions of Catlin, Sidell, Carroll, and Vance Townships. The petition was filed in 1897, but the township wasn't approved until 1899 after a lengthy court battle, partly due to the excellent farmland in the area. The township was originally called Kingsley after a local chapel. Rob Weller lived there for 20 years.[3] Later, local W. T. Baird suggested changing the name for Jamaica, Queens, a borough of New York City, which was named for a northeastern Algonquin Indian tribe.[4]
According to the 2010 census, the township has a total area of, of which (or 99.23%) is land and (or 0.77%) is water.[2] The stream of Jordan Creek runs through this township.
