Queen Anne in Prince George's County, Maryland, United States, is a former port on the Patuxent River.

The head of tidewater on the Patuxent River is at the downstream (4H---a group not affiliated with the National 4H Club) launch site in Queen Anne.

A tobacco inspection station and warehouse was located on Hazelwood, then owned by Thomas Lancaster, one of the town's leading merchants.

[10] By the mid-18th century, upland farming in the Patuxent basin without erosion control led to massive silting of the river.

The ports along the Patuxent quickly filled with silt and could no longer take in ocean-going vessels[10] such as the snows that frequented the town.

[10] During the War of 1812, the Chesapeake Bay Flotilla commanded by Joshua Barney scuttled his entire fleet in the half dozen miles of river below Queen Anne to avoid the vessels being captured by the advancing British.
