Mount Kuring-gai is located 31 kilometres north-west of the Sydney central business district, in the local government area of Hornsby Shire.

The name "Kuring-gai" derives from the Guringai Aboriginal people who were thought to be the traditional owners of the area.

There are several bushwalks starting in the suburb including the Great North Walk and a path to Apple Tree Bay.
