Charles Springer Tavern, also known as the Oak Hill Inn, Four Mile Inn, and Sign of the Three Tons, is a historic inn and tavern located near Wilmington, New Castle County, Delaware, USA.

A stone, two-story, two-bay, gable-roofed section was added about 1780; the roof level, window and door openings and floor levels were subsequently raised on the original log section; and a stone, 1+1⁄2-story lean-to was added on the rear wall of the log section.

Also on the property are the contributing ruins of a stone barn built in 1852, the ruins of a stone springhouse, and a stone mileage marker identifying the location as being four miles from the City of Wilmington.
