Cairo Flats, also colloquially known as Cairo Bachelor Flats or Cairo, is a heritage-listed apartment building in the Melbourne inner city suburb of Fitzroy. Cairo Flats derives its name from the Egyptian capital city. While several theories have been proposed regarding the reason for this name, no official documentation exists to substantiate any of them, leaving the matter open to speculation. Cairo Flats is situated opposite the Royal Exhibition Building in the Carlton Gardens, a UNESCO World Heritage Site. As a result, Cairo also sits within the World Heritage Environs Area (WHEA) overlay that surrounds this precinct.
