Ellen Cashman (1845 – 4 January 1925) was an Irish nurse, restaurateur, businesswoman and philanthropist in Arizona, Alaska, British Columbia and Yukon. Cashman led a rescue party to miners to the Cassiar Country gold mine in the Cassiar Mountains of British Columbia earning her the nickname "Angel of the Cassiar". In Tombstone, Arizona, Cashman raised money to build the Sacred Heart Catholic Church, and did charitable work with the Sisters of St. Joseph. She went to the Yukon during the Klondike Gold Rush for gold prospecting, working there until 1905. She became nationally known as a frontierswoman, with the Associated Press covering a later trip.
