Lexington Avenue, often colloquially abbreviated as "Lex", is an avenue on the East Side of the borough of Manhattan in New York City that carries southbound one-way traffic from East 131st Street to Gramercy Park at East 21st Street. Along its 5.5-mile (8.9-kilometer), 110-block route, Lexington Avenue runs through Harlem, Carnegie Hill, the Upper East Side, Midtown, and Murray Hill to a point of origin that is centered on Gramercy Park. South of Gramercy Park, the axis continues as Irving Place from 20th Street to East 14th Street.

Lexington Avenue was not one of the streets included in the Commissioners' Plan of 1811 street grid, so the addresses for cross streets do not start at an even hundred number, as they do with avenues that were originally part of the plan.

The portion of Lexington Avenue between 14th and 20th Streets is known as Irving Place.

Both Lexington Avenue and Irving Place began in 1832 when Samuel Ruggles, a lawyer and real-estate developer, petitioned the New York State Legislature to approve the creation of a new north/south avenue between the existing Third and Fourth Avenues, between 14th and 30th Streets. Ruggles had purchased land in the area, and was developing it as a planned community of townhouses around a private park, which he called Gramercy Park. He was also developing property around the planned Union Square, and wanted the new road to improve the value of these tracts. The legislation approved, and, as the owner of most of the land along the route of the new street, Ruggles was assessed for the majority of its cost. Ruggles named the southern section, below 20th Street, which opened in 1833, after his friend Washington Irving. The northern section, which opened three years later, in 1836, was named after the Battle of Lexington in the Revolutionary War.
