The Woman's Twentieth Century Club was organized in 1912 for the purpose of individual culture and civic involvement, with Dr. Minerva Cushman as its first president.  For a number of years, the club met in members' homes.  In 1928, an invitation from the Chamber of Commerce to use its building as a meeting place was accepted.  During the same year, Miss Harriett Orcutt, a charter member, donated her large private collection of books to the club for use as a public library.  These books were moved to the Chamber building for that purpose. 

The club joined the Florida Federation of Women's Clubs in 1919, becoming the nineteenth federated club in Florida. An effort was made to build a clubhouse on the property known as Hibiscus Park, for which a lease was granted by the Commongood Society. This was abandoned due to lack of funds. The present clubhouse was acquired from the Miller Family in 1940. Also in 1940, the name was changed to The Ruskin Woman's Club.

Over the years, the club has been instrumental in accomplishing many worthwhile projects in Ruskin.  These include the Ruskin Cemetery and the Ruskin Branch Library which opened in 1966.  From its inception the Ruskin Woman's Club has been an integral part of the social, cultural, and economic development of Ruskin.
