Colonel Matron Kathleen Annie Louise Best, OBE, RRC (28 August 1910 – 15 November 1957) was the first director of the Women's Royal Australian Army Corps.

The 2/5th Australian General Hospital was then re-established in Palestine and reorganised under Best's supervision, but in August 1941 moved again, this time to Eritrea on the African coast.

A month after leaving the AIF she became the Controller of full-time Voluntary Aid Detachments, which in September became part of the Australian Army Medical Women's Service.

In September 1952 she reached the rank of honorary colonel and four years later, in 1956, appointed Officer of the Order of the British Empire.
