Bronx, The, the northernmost borough of New York City and the only part of the city on the mainland. It has the same boundaries as Bronx County. The borough is northeast of Manhattan and separated from it by the Harlem River. The East River separates the Bronx from Queens, to the south. The area of the Bronx is about 43 square miles (111 km2).

Although the Bronx is predominantly residential, there is some industry, mostly along the East River. Pelham Bay Park, in the northeast, covers an area of 2,118 acres (857 hectares); it is the largest park in New York City. The Bronx Wildlife Conservation Park (commonly called the Bronx Zoo) and the New York Botanical Garden are in the central part of the borough. Also here is the Edgar Allan Poe Cottage, where Poe lived from 1846 to 1848. In the northwest, overlooking the Hudson River, is Wave Hill, a 28-acre (11-hectare) public garden and cultural center. Yankee Stadium, home of the New York Yankees of major-league baseball, is in the southwest.

The Bronx has many institutions of higher learning, including Fordham University, the State University of New York Maritime College, and Yeshiva University. Other cultural institutions include the Museum of Bronx History and the Bronx Museum of the Arts.

The Bronx was first settled in 1639 by Jonas Bronck, a Swedish sea captain, and his family. They settled near a river that soon became known as the Broncks' River—the origin of the name Bronx.

The Bronx experienced continuous growth between 1840 and 1930, largely as a result of the arrival of immigrants from Europe. The western part of the Bronx was annexed by New York City in 1874; the eastern part, in 1894. In 1898 these two parts were joined as the borough of the Bronx. In the mid-20th century, the Bronx became notorious for the urban decay it suffered, especially in its southern neighborhoods. In the 1980's and 1990's new waves of immigrants settled the Bronx from west Africa and southeast Asia.
