Biddles Corner is a location in St. George's Hundred, New Castle County, Delaware, United States.

Biddles Corner is at the intersection of U.S. Route 13 and Port Penn Road just east of the Biddles Corner toll plaza on the Delaware Route 1 toll road south of the Chesapeake and Delaware Canal.

[3] The original property, consisting of 179 acres, was granted to Leonard Vandegrift by Thomas and William Penn in 1708 and became the Biddles Corner farm.

The 120 ft (37 m)-tall Liston Range Rear Lighthouse was built circa 1876 to 1877 east of its present site and was moved near Biddles Corner in 1906.

[13] In 1884, the Fort Penn Grange was building a large hall at Biddles Corner with an exhibition room.
