Phyllis Mander-Jones MBE (2 January 1896 – 19 February 1984) was an Australian born librarian and archivist who helped establish the archival profession in Australia.

[1][2] Phyllis Mander-Jones was born in Homebush, Sydney, Australia, the eldest child of physician George Mander Jones and his wife Margaret Fleming (née Arnott).

[1] Both parents had commercial connections: George was the grandson of retailer David Jones, whilst Margaret was the daughter of Australia's leading biscuit manufacturer, William Arnott.

[7] Mander-Jones was appointed Mitchell Librarian in November 1946 and began the work of modernising the library in the wake of the difficult war years.

Drawing on her experience in bibliography she established standards in recording collections, created finding aids to assist researchers, and giving due care to the processing of original materials: manuscripts, pictures and maps.

To this end she acquired significant original materials such as records of the Supreme Court of New South Wales and the second collection of Macarthur papers.

In retirement, Mander-Jones returned to Australia and pursued her interest in bibliography, contributing most notably to J.C. Beaglehole's The Life of Captain Cook (1974) as well as researching the family history of her Arnott ancestors.
