New York State Route 270 (NY 270) is a north–south state highway in western New York in the United States. It runs through rural and wooded areas of the town of Amherst in Erie County and the town of Pendleton in Niagara County. The southern terminus of the route is at an intersection with NY 263 south of the hamlet of Getzville. Its northern terminus is at a junction with NY 31 and NY 93 west of the city of Lockport. The entirety of NY 270 is known as Campbell Boulevard, named after New York State Senator William W. Campbell of the Niagara–Orleans district. NY 270 was assigned as part of the 1930 renumbering of state highways in New York. The route once extended as far south as NY 5 and as far north as NY 104; however, it was gradually truncated to its current length as other routes were realigned or extended onto NY 270's alignment.
