Templeton is an unincorporated community in Bolivar Township, Benton County, in the U.S. state of Indiana.
Two railways, the Cleveland, Cincinnati, Chicago and St. Louis (the "Big Four") and the Lafayette, Muncie and Bloomington (the "Nickel Plate"), intersected at the site.
The town gained it first grain elevator in 1874 and a tile factory in 1881 which operated two large, steam-powered kilns.
By 1883 the town's businesses included David Lanham & Co. and Finch & Son (both purveyors of dry goods and groceries), Joseph Dehart's notions and butcher shop, John Rosa's grocery, Dr. C. W. Fall (physician and pharmacist), Jasper Bristow (physician) and the Railroad House.
U.S. Route 52 passes along the town's northeast side, and the Kankakee, Beaverville and Southern Railroad, which comes in from the east, splits into two lines that head west and northwest.
