The 1881 Martin's Mill Covered Bridge is a wooden covered bridge spanning Lull's Brook on Martinsville Road in Hartland, Windsor County, Vermont. The bridge was built by James Tasker, who covered bridge historian R.S. Allen describes it as one of the most prolific bridgewrights in Windsor County.

Tasker most often built bridges that were a modified version of a kingpost truss; this bridge is the more common Town lattice style. It is, along with the Willard Covered Bridge, one of two surviving 19th-century covered bridges in Hartland.

The bridge is a single-span Town lattice truss, resting on concrete abutments. It is 137.1 feet long, with portals overhanging the ends by 4 feet. The length of the largest span is 134.8 ft. Its total width is 19.5 feet, with a roadway width of 16.5 feet (one lane), and a vertical clearance above deck clearance of 9.3 ft. The exterior of the bridge is clad in vertical board siding, which wraps around for a short distance on the insides of the portals. The roof is metal.

Of the over 500 covered bridges that were built in the state of Vermont, as of 2019, only 104 remain.
