| mapframe-wikidata = yes 345 Park Avenue is a 634 ft skyscraper in the Midtown Manhattan neighborhood of New York City. It occupies an entire city block bounded by Park Avenue, Lexington Avenue, 51st Street, and 52nd Street.

Completed in 1969, with 44 floors, the building was designed by Emery Roth & Sons. The building has its own assigned ZIP Code, 10154, making it one of 41 buildings in Manhattan that had their own ZIP Codes . It is near the Racquet and Tennis Club and Park Avenue Plaza to the northeast; the Seagram Building to the north; 599 Lexington Avenue to the northeast; and St. Bartholomew's Episcopal Church and the General Electric Building to the south.

History

It is built on the block containing the former site of the Hotel Ambassador, which had opened in 1921, as well as several townhouses and tenement buildings. The Hotel Ambassador was sold to Sheraton Hotels in 1958 and renamed the Sheraton-East; it was demolished in 1966. From 1998 to 2000, the exteriors of 345 Park Avenue were used as the headquarters of CSC and Continental Corp. in Sports Night, a TV series created by Aaron Sorkin. In 2024, the owner Rudin Management announced that it would build a fitness center and restaurants for the building's workers.

On July 28, 2025, four people were killed and another injured in a mass shooting when 27-year-old Shane Tamura shot people with an AR-style rifle in the lobby and on the 33rd floor of the building. Tamura later killed himself.

Plaza

The skyscraper is set back behind a 20,690 sqft public plaza that spans the entire blockfront on Park Avenue and extends back along a portion of the building's 51st Street frontage. The plaza allowed developer Samuel Rudin to obtain a zoning "bonus" for including open space under the terms of the city's 1961 Zoning Resolution; the plaza was placed on the west side of the site to be compatible with the adjacent open spaces at the Seagram Building and St. Bartholomew's Church. The plaza includes a 12 ft sculpture by Robert Cook entitled "Dinoceras" that was dedicated in 1971 and commissioned by Jack and Lewis Rudin.
