The Oregon Federation formally was organized in 1940 and affiliated with the NFRW that same year. The state has seven districts and 24 clubs.
The Oregon Federation had its beginnings in 1935 when Irene Gerlinger and Ella Allen Scott of Portland organized a women's political group, Republican Women of Oregon Inc. A month later, the group also organized under the auspices of Pro America, founded by Mrs. Theodore Roosevelt. In 1940, the group was approved to become a member of the NFRW and maintained membership in both organizations. By 1945, two more Republican women's groups had been founded. Ultimately, members from all three organizations wanted to unite the strength of Republican women to work "toward one goal, Republican victories in Oregon."
Today, members educate Oregon voters about Republican philosophy and help elect Republican candidates by volunteering countless hours to campaigns. The clubs participate in local community events such as parades and fairs. They provide scholarships, sponsor essay contests, and assist in food and clothing programs for the needy.
