The 1910 Harmon's Covered Bridge is a historic wooden covered bridge located in Washington Township in Indiana County, Pennsylvania. It is a 41-foot-long (12 m), town truss bridge that crosses the South Branch Plum Creek and is one of only four remaining covered bridges in Indiana County. Harmon Covered Bridge is the “youngest” of these bridges.

Harmon Bridge was named after Civil War veteran J.S. Harmon, a local farmer who survived the infamous Confederate POW camp in Andersonville, Georgia. Built by John R. Carnahan, costing $525, Harmon Bridge is constructed with town lattice trusses. It is considered a companion bridge to Trusal Bridge, located also on the south branch of Plum Creek just off Five Points Road. Both bridges are within sight of each other and are a near mirror image with a unique trapezoid shape.

A historical marker at one end of the bridge explains its history. The bridge was bypassed in 1984 but remains open to foot traffic.

Harmon's Bridge was listed on the National Register of Historic Places in 1979.
