834 Fifth Avenue is a luxury residential housing cooperative on the Upper East Side of Manhattan, New York City.

It has been called "the most pedigreed building on the snobbiest street in the country’s most real estate-obsessed city" in an article in the New York Observer newspaper.

[5] This status is due to the building's overall architecture, the scale and layout of the apartments, and the notoriety of its current and past residents.

[6] The building was constructed in 1931, and was one of the last luxury apartment houses completed before the Great Depression halted such projects in New York City.

The building uses setbacks at the upper floors to create terraces for several apartments and provide visual interest from a distance.

In addition, the cooperative's board is rumored to require potential buyers to possess liquid assets in excess of ten times the value of the purchased unit.

The original design for 834 called for a midblock 120-foot-wide building, but it was asymmetrically extended southward during construction after a holdout corner mansion was acquired by the developer.

[7] Because this happened with the steel frame of the building's structure already in place, the extra 30 feet of frontage would be allocated as a line of duplex apartments, so that the original developer blueprints remained more or less intact.

834 Fifth Avenue has historically been home to a large number of founders and heirs of major American family fortunes.

In addition, 834 Fifth Avenue has welcomed a higher percentage of entrepreneurs and self-made business people than its peer buildings.

When Charlie Chaplin was in New York City during his contract negotiations with Mutual Film, and found out that his first love, Hetty Kelly, was staying with her sister, Mrs. Ethel Margaret Kelly Gould (wife of Frank Jay Gould), at 834 Fifth Avenue, he stalked the place.
