The Saw Mill River Parkway (also known as the Saw Mill Parkway or the Saw Mill) is a limited-access parkway that extends for 28.93 miles (46.56 km) through Westchester County, New York, in the United States. It begins at the border between Westchester County and the Bronx, as the continuation of the Henry Hudson Parkway leaving New York City, and heads generally northeastward to an interchange with Interstate 684 (I-684). At its north end, the parkway serves as a collector/distributor road as it passes east of the hamlet of Katonah. The parkway is named for the Saw Mill River, which the highway parallels for most of its length.

The Saw Mill serves as an important connection from the Taconic State and Sprain Brook parkways to the Tappan Zee Bridge and New York State Thruway. It is an expressway, but not a freeway as several of its exits are signalized at-grade intersections. The Saw Mill River Parkway is inventoried by the New York State Department of Transportation (NYSDOT) as New York State Route 987D (NY 987D), an unsigned reference route designation.
