Elizabeth Williams Berry (June 21, 1854 – March 26, 1969), who became known as Mother Berry some time after 1900, was an Australian-born jockey who rode in multiple nations disguised as a man, using the name Jack Williams. After moving to the United States about 1900, she married, and gained the nickname "Mother" after being granted custody of a runaway boy. She retired from jockeying to become a horse trainer. Berry and her husband settled in Helena, Montana, where, at age 111, she was declared the oldest person in Montana at the time. She lived to see women ride as licensed jockeys in 1969 and died at age 114.
