Elisabeth Susanne Heyerdahl (1858–1921) was a Norwegian Conservative politician, teacher, and a strong supporter of women's involvement in politics. She was one of the first women to be elected to Christiania's City Council. In 1910, she co-founded the Conservative Party's Women's Club (Høirekvinders klub), heading the organization for a number of years. In 1909, she became the first woman to serve on the Conservative Party's central committee.[1][2]
