Highlandtown Lake is a man-made lake located in Washington Township, Columbiana County, Ohio. It was created in 1966 when the State of Ohio built a dam impounding 170 acres (0.69 km2) of water on the upper drainage of the Little Yellow Creek. A lot of habitat improvement was done on what would be the bottom of the lake prior to the impoundment. It has about 5 miles (8.0 km) of shoreline and a maximum depth of about 26 feet (7.9 m). The lake is about 1,100 feet (340 m) above sea level.

Its capacity is 5,710 acre-feet (0.00704 km3). Normal storage is 2,700 acre-feet (0.0033 km3). It drains an area of 5.8 square miles (15 km2).
