The Upper West Side is a neighborhood in the borough of Manhattan, New York City, that lies between Central Park and the Hudson River and between West 59th Street and West 116th Street. The Upper West Side is sometimes also considered by the real estate industry to include the neighborhood of Morningside Heights.
Like the Upper East Side, the Upper West Side is an upscale, primarily residential area with many of its residents working in more commercial areas in Midtown and Lower Manhattan. It has the reputation of being home to New York City's cultural, intellectual hub (with Columbia University located at the north end of the neighborhood), and artistic workers (with Lincoln Center located at the south end), while the Upper East Side is traditionally perceived to be home to commercial and business types. The neighborhood is also referred to for short as just the West Side or the UWS.
The Upper West Side is bounded on the south by 59th Street, Central Park to the east, and the Hudson River to the west. Its northern boundary is somewhat less obvious. Although it has historically been cited as 110th Street, which fixes the neighborhood alongside Central Park, it is now sometimes considered to be 125th Street, encompassing Morningside Heights. This reflects demographic shifts in Morningside Heights, as well as the tendency of real estate brokers to co-opt the tony Upper West Side name when listing Morningside Heights and Harlem apartments. The area north of West 96th Street and east of Broadway is also identified as Manhattan Valley. The overlapping area west of Amsterdam Avenue to Riverside Park was once known as the Bloomingdale District.
From west to east, the avenues of the Upper West Side are Riverside Drive (12th Avenue), West End Avenue (11th Avenue), Broadway, Amsterdam Avenue (10th Avenue), Columbus Avenue (9th Avenue) and Central Park West (8th Avenue). The 66-block stretch of Broadway forms the spine of the neighborhood and runs diagonally north/south across the other avenues at the south end of the neighborhood; above 72nd Street Broadway runs north parallel to the other avenues. Broadway enters the neighborhood at its juncture with Central Park West at Columbus Circle (59th Street), crosses Columbus Ave. at Lincoln Square (65th Street), crosses Amsterdam Ave. at Verdi Square (72nd Street), and then merges with West End Ave. at Straus Park (aka Bloomingdale Square, at 107th Street).
