State Route 271 (SR 271), also known as Belfast Farmington Road, is a short 6.3 miles (10.1 km) long north–south state highway in Marshall County, Tennessee.

It serves as a connection between the communities of Belfast and Farmington.

It winds its way north to cross a bridge over a creek before passing through mix of rural farmland and hilly wooded terrain for several miles.

The highway then crosses another creek before entering Farmington and coming to an end at an intersection between US 31A (SR 11) and SR 64.
