U.S. Route 6 (US 6) in Massachusetts is a 117.952-mile-long (189.825 km) portion of the cross-country route connecting Providence, Rhode Island, to Fall River, New Bedford, and Cape Cod. In the Fall River and New Bedford areas, US 6 parallels Interstate 195 (I-195). On Cape Cod, US 6 is a highway interconnecting the towns of the area. The freeway section in this area is also known as the Mid-Cape Highway. The highway is also alternatively signed as the "Grand Army of the Republic Highway".

The section of the Mid-Cape Highway between exit 78 and the Orleans rotary is known to locals as "Suicide Alley" due to the number of fatal accidents that happen on this stretch of two-lane divided freeway with only a berm separating the lanes of traffic.
