Florence Terry Griswold (May 28, 1875 – July 7, 1941) was an American cattlewoman and rancher from Texas. She was the first woman delegate of the Texas Cattle Raisers Association to attend the Trans-Mississippi Convention and for several years, the only woman delegate. A staunch supporter of women's equality, she worked as a suffragist, served as a Republican National Convention Delegate for many years and later fought for equal pay for women. She is most known as the founder of the Pan-American Round Tables in 1916, which has grown from a single club begun in San Antonio, Texas, to an international NGO with over 1400 branches.
