Gerda Henrietta Margareta Planting-Gyllenbåga (1878–1950) was a Swedish suffragist and social welfare expert who was deeply engaged in the women's movement at the local and national levels as a member of the Swedish Association for Women's Suffrage (LKPR). She devoted considerable attention to public education, organizing courses to promote women's enlightenment. In 1911, in collaboration with LKPR, she coordinated the nation-wide educational courses funded by Martina Bergman-Österberg. After spending several years in her native Skara, in 1916, she moved to Stockholm as director of CSA (Centralförbundet för Socialt Arbete), the Swedish social welfare association.
