The Wilbraham is an apartment building at 282–284 Fifth Avenue and 1 West 30th Street in the Midtown South neighborhood of Manhattan in New York City. The nine-story structure was designed by David and John Jardine in the Romanesque Revival style, with elements of the Renaissance Revival style, and occupies the northwestern corner of 30th Street and Fifth Avenue. It was built between 1888 and 1890 as a bachelor apartment hotel. The New York City Landmarks Preservation Commission has designated the Wilbraham as an official city landmark, and the building is listed on the National Register of Historic Places.

The building occupies a rectangular site and has a facade that is divided horizontally into three sections. The lowest two stories are clad in rusticated blocks of New Jersey brownstone, with storefronts near the western and eastern ends of the facade. The third through sixth stories are clad in Philadelphia red brick, the seventh story is clad in ashlar, and the eighth story is located within a mansard roof. The Wilbraham retains much of its original layout, which is composed of storefronts and a lobby on the lowest two floors, as well as apartments on the third through eighth floors. The building originally had 42 apartments and five servants' quarters, which by the 2010s had been consolidated into 38 apartments. Its bachelor flats each consisted of a bedroom and parlor, with a bathroom but no kitchen; the communal dining room was on the eighth floor.

The building was a speculative development by Scottish-American jeweler William Moir, at a time when clubs, hotels, and the first blocks of "French flats" were being developed in the area. When the Wilbraham opened in May 1890, china and glass importer Davis Collamore & Co. leased two floors of showrooms. John J. Gibbons, the leader of Davis Collamore & Co., bought the building in 1908 and sold it in 1927. The Metropolitan Life Insurance Company took over the Wilbraham in 1934 and renovated it over the next year, adding some units with kitchens. By the 21st century, the building was still mostly residential.

The Wilbraham is at the northwestern corner of 30th Street and Fifth Avenue in the Midtown South neighborhood of Manhattan in New York City, at the northern edge of the NoMad neighborhood. The land lot is rectangular and measures around 5,000 square feet (460 m²), with a frontage of 40 feet (12 m) on Fifth Avenue and 125 feet (38 m) along 30th Street. To the south of the Wilbraham are the Marble Collegiate Church and old Holland House. Other nearby buildings include the Gilsey House to the west, the Grand Hotel on the same block to the northwest, the Hotel Wolcott on the same block to the north, the Colony Club building to the east, and the Church of the Transfiguration to the southeast.

During the mid-19th century, the stretch of Fifth Avenue between 23rd Street and 42nd Street had contained brownstones and mansions for some of New York City's wealthiest residents, as well as churches. Many hotels and social clubs opened in what is now NoMad following the opening of the Fifth Avenue Hotel in the 1850s, followed by apartment hotels, apartment buildings, Broadway theaters, and stores in the 1870s. The area's wealthiest residents moved uptown in the 1880s, but the neighborhood remained fashionable for clubs, hotels, and the first blocks of "French flats". When the Wilbraham opened in 1890, the surrounding area contained many Broadway theaters, men's clubs, Madison Square Garden, and Delmonico's restaurant. Even in the 21st century, the area contained a large number of apartment buildings, scattered among the commercial and office structures of the neighborhood.

The Wilbraham was designed by brothers David and John Jardine. It is eight stories under a verdigris copper-covered mansard roof. The building's design largely contains elements of the Romanesque Revival style, with elements of the Renaissance Revival style. Some parts of the design, such as rock-faced walls and round arches, were influenced by the Richardsonian Romanesque style developed by H.H. Richardson. The building also has a penthouse and a basement, though this is not included in the floor count.

The Wilbraham is clad in Philadelphia brick and brownstone from quarries in Belleville, New Jersey, with wrought- and cast iron, and has sash windows with wooden frames. The Fifth Avenue elevation of the facade is divided vertically into two bays, while the 30th Street elevation is divided into seven bays. On both elevations, the facade is divided horizontally into three sections: the base, midsection, and capital.

The base is clad in rusticated blocks of brownstone, with alternating decorative bands and rock-faced stone, above a water table of gray polished granite. There are three pairs of bays (one on Fifth Avenue and two on 30th Street), which contain storefronts. On both elevations, the ground-story storefronts have been modified from their original design and are topped by canopies and sign boards. Some of the ground-story openings are covered with roller shutters.
