Clayfield is an inner northern suburb in the City of Brisbane, Queensland, Australia. It is approximately 7 kilometres (4 mi) from the Brisbane CBD. Clayfield is bordered to the north by Nundah, to the East by Ascot and Hendra, to the west by Wooloowin and to the South by Albion.

Its name derives from the fine white-grey sedimentary clay mined in Albion, between Morgan and Sykes Street, used in the brickworks that once existed between Oriel Road and Reeve Street near Sandgate Road. This industry, once known as "the clay fields", was instrumental in the residential surge of European settlement of inner-north Brisbane.

Kalinga Park and the Kalinga locality lay on the northern limit. Clayfield also encompasses the locality of Eagle Junction.
