The Bath Covered Bridge is a historic covered bridge over the Ammonoosuc River off US 302 and NH 10 in Bath, Grafton County, New Hampshire.  Built in 1832, it is one of the state's oldest surviving covered bridges. 

The Bath Covered Bridge is located on the west side of the village center of Bath, carrying West Bath Road over the Ammonoosuc River. The bridge has a total length of over 390 feet and a roadbed that is just over 22 feet wide. The bridge consists of four spans supported by Burr trusses, resting on stone piers and abutments, and is finished with vertical board siding. When originally built, it had only three spans, but when the bridge was raised in the 1920s, a third pier was added, as were laminated arches to strengthen the bridge.

The current structure is the fifth bridge to stand on this site. The first was constructed in 1794 at a cost of $366.66. That bridge was demolished by a flood and replaced in 1806 at a cost of $1,000. The second and third bridges were also destroyed by floods but were immediately replaced in 1820 and again in 1824. The fourth bridge was destroyed by fire in late 1830. Rebuilding efforts began in March 1831 when $1,400 was allotted to cover the construction of two stone abutments and piers along with the purchase of other materials. In March 1832, an additional $1,500 was allotted to complete the construction. It appears that the fifth bridge was completed by early 1832. When it was first built, the bridge had hewn arches. New overlapping arches were added when the bridge was raised over the railroad in 1920. At one time, there was a sign posted at the bridge which prohibited riding horses across the bridge at a trot. It was believed that the impact of trotting horses could cause the structure to fall apart.

The bridge serves a primarily rural residential population and sees relatively little traffic. The bridge was closed to traffic in October 2012 for safety, structural, and cosmetic reasons. After 21 months and $3 million in repairs, it re-opened in August 2014.

Of the 400 covered bridges that once stood in the state of New Hampshire, as of 2019 only 54 remain.

It was listed on the National Register of Historic Places in 1976 and underwent a major rehabilitation in the 2010s.
