Hawthorne Circle was a notably dangerous traffic circle located in Hawthorne, New York, United States until 1971 when it was replaced with a three-level interchange. The circle once connected two busy highways, the Taconic State Parkway and the Saw Mill River Parkway. It also accessed to the Bronx River Parkway by way a segment of the Taconic Parkway. The Sprain Brook Parkway, whose northern terminus lies just south of the circle, was not completed until 1980, eight years after the circle was converted to an interchange.
