Frank Hamilton Talbot AM (3 January 1930 – 15 October 2024) was a South-African born Australian ichthyologist and marine biologist. He was former director of the Australian Museum and the only Australian to have become director of the Smithsonian Natural History Museum. His research and his work at the institutions he led have had a lasting impact on science, academia, and public education, and the Lizard Island Research Station, founded by him in 1973, continues his work. He has had two species of fish named after him, and the Australian Museum holds the annual Talbot Oration in his honour.
