Massachusetts Route 71 and New York State Route 71 (NY 71) are adjoining state highways in the states of Massachusetts and New York in the United States. The two highways form a continuous roadway connecting NY 22 in Hillsdale, Columbia County, New York, to Route 23 and Route 41 in Great Barrington, Berkshire County, Massachusetts. Combined, Route 71 and NY 71 extend for 7.93 miles (12.76 km) as a two-lane road through mostly rural areas in the Taconic Mountains, serving only small, unincorporated communities in both states. Both routes are part of the Henry Knox Trail.

The New York half of the highway was rebuilt by the state in the late 1920s and designated as NY 71 as part of the 1930 renumbering of state highways in New York. Its Massachusetts continuation was unnumbered until the early 1930s when it was assigned Route 69. Around the end of the decade, Route 69 was renumbered to Route 71 to match the New York number. At 2.30 miles (3.70 km) in length, NY 71 is the shortest two-digit state highway in New York.
