Rachel Don (née Hull; 23 July 1866 – 4 September 1941) was an accredited Methodist local preacher who became a local and national leader in the Women's Christian Temperance Union New Zealand (WCTU NZ), serving as president from 1914 to 1926. Under her leadership, the WCTU NZ focused on white slavery, promoting national prohibition, and expanding women's career opportunities, especially in the New Zealand Police Force and judicial system. She represented New Zealand at a world-wide temperance convention in London in 1920, and at the U.S. Woman's Christian Temperance Union Jubilee in 1924. She served in many other local charitable organisations, and after visiting India, became a fervent leader of the Dominion Stocking League to send refurbished clothing for impoverished children and women to Christian mission stations in India.
