Annie Pearson, Viscountess Cowdray GBE (née Cass; 4 June 1860 – 15 April 1932) was an English society hostess, suffragist and philanthropist. She was nicknamed the Fairy Godmother of Nursing due to her financial patronage of the Royal College of Nursing and her work to promote district nursing throughout England and Scotland. She served as the President of the Women's Liberal Federation from 1921 until 1923 and was also the Honorary Treasurer of the Liberal Women's Suffrage Union. She was the only woman to hold the office of High Steward of Colchester, serving from 1927 until her death in 1932.
