The Municipality of North Illawarra was a local government area in the Illawarra region of New South Wales, Australia. It covered the area from Fairy Meadow to Bellambi.
Its council chambers were at Fairy Meadow, in a building that has since been repurposed.
The shire was amalgamated with the then-Municipality of Wollongong, Bulli Shire and Central Illawarra Shire to form a Municipality of Greater Wollongong, which was at the same time proclaimed as the City of Greater Wollongong, on 24 September 1947.
