Route 3 is a highway in northern and central Missouri. Its northern terminus is at Route 11 south of Kirksville; its southern terminus is at Route 5/Route 240 northwest of Fayette.

Route 3 was initially Route 67, designated in 1922 between Rocheport and Fayette. It was renumbered in 1926 due to US 67. In 1934/1935, the route extended north to US 36 in Callao. The next year, the original portion from Rocheport to Fayette became part of Route 240. In 1953/1954, the route extended north to Kirksville, its current terminus.
