Phi Mu (ΦΜ) is the second oldest secret organization for women in the United States. It was founded at Wesleyan College in Macon, Georgia on January 4, 1852 and was announced publicly on the fourth of March of the same year. The original name for this group was the Philomathean Society. Phi Mu's three founders are Mary Myrick Daniel, Mary Dupont Lines, and Martha Hardaway Redding. In 1904, the Philomathean Society became the Greek letter organization Phi Mu. The term "sorority" had not yet been coined, and the organization is called a "fraternity for women."

Today, Phi Mu is a strong Greek organization, with over 150 collegiate chapters across the United States and over 140,000 initiated sisters. Phi Mu's national philanthropy is Children's Miracle Network, which raises money to support children's hospitals across the country.

In 1904, Phi Mu became a member of the National Panhellenic Conference and added additional chapters.
