New York State Route 206 (NY 206) is a state highway in the Southern Tier of New York in the United States. It runs through some lightly populated regions along the state's southern border, from Central New York to the Catskills. It begins near a busy intersection with Interstate 81 (I-81) at Whitney Point and runs east from there through Greene. The eastern terminus is located at a junction with NY 17 (future I-86) at Roscoe in Sullivan County. It is one of the longest three-digit routes in New York, and the only long one not associated with a two-digit route or a former U.S. Route. Yet due to its location it sees little traffic, although for much of its length it follows the route of a main 19th century thoroughfare, the Catskill Turnpike. It is primarily a long shortcut around Binghamton.

NY 206 was assigned as part of the 1930 renumbering of state highways in New York, but only from Bainbridge to Downsville. NY 206 was extended west to Whitney Point in the early 1940s; another extension in the late 1970s moved the route's eastern terminus to Roscoe. Prior to becoming NY 206, the Whitney Point–Greene segment was once New York State Route 219 and New York State Route 383 while the portion from Coventry to Bainbridge was previously New York State Route 218.
