Thompson Street (Manhattan)  Thompson Street is a street in the Lower Manhattan neighborhoods of Greenwich Village and SoHo in New York City, which runs north–south, from Washington Square Park at Washington Square South (West Fourth Street) to the Avenue of the Americas (Sixth Avenue) below Grand Street, where the street turns right to Sixth Avenue; it thus does not connect with Canal Street just a half block south of the turning point. It runs parallel to and between Sullivan Street (to the west), and LaGuardia Place (formerly Laurens Street) which becomes West Broadway (to the east). Vehicular traffic goes southbound. The street was named for Revolutionary War Brigadier General William Thompson, who served in New York and Canada.
