Jessie McHardy White, MBE, RRC (née Williamson; 24 July 1870 – 26 October 1957) was an Australian army principal matron.

[3] In 1906, White took charge of a private hospital in Melbourne and became a member of the Australian Army Nursing Service Reserve (AANS).

In October 1914, White set sail with the initial group of the Australian Imperial Force (AIF) and reached Egypt on 4 December.

In early 1916, due to a reorganization of the Australian Army Medical Corps and the AANS, she was appointed as the principal matron of the AIF in England.

After Matron-in-Chief Evelyn Conyers arrived in London, White returned to Australia in August, having been awarded the Royal Red Cross (1st Class) for her exceptional contributions.
