The Jacks Mountain Covered Bridge (officially known as the G. Donald McLaughlin Memorial Covered Bridge) is a historic covered bridge in Hamiltonban Township, Adams County, Pennsylvania.

Jacks Mountain Bridge was built in 1890 by Joseph Smith and is a 75-foot-long and 15 feet 6 inches in width, Burr truss bridge with narrow horizontal siding and a tin-covered gable roof. The bridge crosses Tom's Creek. It is one of 17 covered bridges in Adams, Cumberland, and Perry Counties.

This Burr-truss-covered bridge is the only covered bridge in Adams County still used for daily motor vehicle traffic. Jack's Mountain Bridge is the only covered bridge in Adams County that uses traffic lights to control traffic flow across the one-lane structure.

The state of Pennsylvania owns the bridge, and of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.

Length of largest span:  64 feet
Total length:  75.1 feet
Deck width:  13.5 feet
Vertical clearance above deck:  10.7 feet

This bridge was listed on the National Register of Historic Places in 1980 as "Jacks Mountain Bridge," but its name was officially changed to the "G. Donald McLaughlin Memorial Bridge" in 1998 in memory of the gentleman who spearheaded the bridge restoration campaign.
