Pohick Creek is a 14.0-mile-long (22.5 km)[5] tributary stream of the Potomac River in Fairfax County in the U.S. state of Virginia.

Pohick Creek forms in the vicinity of Burke and flows southeast past the western edge of Fort Belvoir to empty into the tidal Pohick Bay, which itself empties, along with Accotink Bay, into Gunston Cove, an embayment of the tidal Potomac River.

Pohick Creek is a popular stream for whitewater kayaking, rafting, and paddling, providing Class II and III rapids along a 5.5-mile (8.9 km) stretch between Hooes Road (Virginia Secondary Route 636) and the Richmond Highway (U.S. Route 1) at Lorton.

It then meets the Potomac River in Pohick Bay about 0.5 miles north of Springfield Farms.
