Route 35 is a state highway in Connecticut, located entirely within the town of Ridgefield, Fairfield County.

Route 35 begins at the New York state line (where it continues west as NY 35) and heads east along South Salem Road and West Lane until Route 33 in downtown Ridgefield, about 1.8 miles (2.9 km) east of the state line.

Route 35 then proceeds in a northeast direction until it meets US 7 about 2.7 miles (4.3 km) later.

A small portion south of Danbury was also assigned as part of U.S. Route 7 about a year later.

Originally, Route 35 used West Lane from the state line to Main Street.
