Sir Albert Cherbury David Rivett KCMG FRS FAA (4 December 1885 – 1 April 1961) was an Australian chemist and science administrator.

In 1910 Rivett spent six months at the Nobel Institute of Physical Chemistry at Stockholm working with the Director, Svante Arrhenius.

In 1914 he was organising secretary of the 84th meeting of the British Association for the Advancement of Science, with the committee chaired by David Orme Masson.

In August 1915 he accepted a commission in the Australian Army Medical Corps Reserve, but from 1917 he was involved in the production of pure ammonium nitrate, used for explosives, at the British munitions works at Swindon.

The understanding gained there led to the publication in 1924 of The Phase Rule and the Study of Heterogeneous Equilibria, and to an appreciation of the value of fundamental research for industrial applications.
