Westernport is a town in Allegany County, Maryland, United States, along the Georges Creek Valley.

Westernport's first settlement is identified on a French military map dating from 1758.

Some time in the mid-1790s, the name was changed to Westernport, with the town being the westernmost navigable port on the Potomac River.

In the late 18th century and early to mid part of the 19th century, coal and timber was loaded onto flatboats where George's Creek empties into the Potomac, then floated down to near Great Falls, Virginia, where the goods were unloaded, the boats broken up to sell as lumber, with the operators walking back to Westernport.

Within the town limits, Maryland Route 937 also serves locals, having formerly been the alignment of MD 36.
