Soldier's Bridge is a former settlement in Lassen County, California. It was located 16 miles (26 km) southeast of Susanville.
In the summer of 1860, First Lieutenant Hamilton from the San Francisco Presidio and fifty men built a bridge at the site, whence the name.
Soldier's Bridge was on the Nobles Emigrant Trail.
A post office operated at Soldier's Bridge from 1864 to 1867.
