The Nobleton Library opened its doors in the spring of 1968. The Nobleton Lion's Club built the original structure, on the King Road where the Fire Hall now stands, and local citizens donated the collection of books. The library was opened for five and a half hours each week and was staffed by fifteen volunteers.

In 1969, the libraries in King City, Nobleton, and Schomberg amalgamated to form King Township Public Libraries. In 1975, the building was renovated to add 400 square feet. The hours increased to twenty-three and a half per week and the staff consisted of four part-time adults and three student pages.

On September 9, 1987, the new Nobleton Public Library branch opened its doors at the present location, Sheardown Drive and Hwy. 27. The hours were expanded to thirty hours per week with a part-time staff of four adults and three student pages. The collection also grew with the addition of videos, talking books, a French collection, compact discs, toys, and large print books. The card catalogues were rendered obsolete when the library became automated in September 1988. In 1998 Nobleton went on-line to the Internet along with the other KTPL branches.
