Route 101 is a state highway in northeastern Connecticut running from Pomfret to the Rhode Island state line in Killingly. The road originated as a 19th-century toll road known as the Connecticut and Rhode Island Turnpike. Route 101 was designated along the modern alignment in 1935 when an earlier Route 101 was renumbered to U.S. Route 44.

Route 101 starts at U.S. Route 44 as Mashamoquet Road then Killingly Road in the town of Pomfret. It runs along the Mashamoquet Brook State Park before intersecting with Route 169. It proceeds eastward, soon passing over the Quinebaug River into the town of Killingly. East of the river, the road becomes known as Hartford Pike. Route 101 then intersects Interstate 395 and Route 12, then passes near Chase Pond, a small pond related to the Chase Reservoir. Route 101 then passes between two large lakes; on the north, the Middle Reservoir (also known as the Chestnut Hill Reservoir), and on the south, the Bog Meadow Pond. It passes by more reservoirs, as it reaches its end at the Connecticut Rhode Island border. Route 101 continues in Rhode Island as Rhode Island Route 101.
