Beaverdam is a village in Richland Township, Allen County, Ohio, United States.

[5] The village was so named on account of there being beaver dams near the original town site.

[8] According to the United States Census Bureau, the village has a total area of 0.61 square miles (1.58 km2), all land.

Currently Beaverdam's economy is dominated by three large truck stops on what is now the junction of Interstate 75 and U.S. Route 30.

This required exit enhanced the village's function as an area for refueling of vehicles.

US 30 is now a continuous four-lane highway in this part of Ohio that bypasses Beaverdam, but the significance of the junction as a major fuel stop has not been diminished.
