Chater House (Chinese: 遮打大廈; Jyutping: ze1 daa2 daai6 haa6) is an office tower in Central, Hong Kong.

[1] Following the Praya reclamation of 1890–1904, a building was constructed and opened in 1905, that served as offices of Canadian Pacific Ocean Services (G/F) and Hong Kong, Canton & Macao Steamboat Company (1/F).

Hongkong Land later acquired the adjacent King's Building and demolished it in 1958 to complete the Union House complex.

The 23-storey building,[2] initially called Union House (於仁大厦; 於仁大廈; Yūrén Dàshà; jyu1 jan4 daai6 haa6), was completed in 1962, and had a total floor space of 34,000 square metres (370,000 sq ft).

The site was again redeveloped by Hongkong Land when the new Hong Kong International Airport opened in 1998.

[7] The building is linked to the Central Elevated Walkway, also owned by Hong Kong Land.

In 2014, the display of Antony Gormley's art installation Event Horizon at Chater House was cancelled when US investment bank JPMorgan, which has offices in the building, asked Hongkong Land – the sponsor of Event Horizon – to cancel its support for the show after bank employee Dennis Li Junjie[8] jumped to his death from the building's roof.
