Old Cargills Building is a colonial-era structure located on York Street in Colombo Fort.

The building was once the residence of the former Dutch military commander of Galle, Captain Pieter Sluysken, and the first British Governor of Ceylon, Sir Frederick North.

In 1896, after the building was acquired by British businessmen William Miller and David Sime Cargill, the current structure was completed in 1906.
