Graham Edward Budd is a British palaeontologist. He is Professor and head of palaeobiology at Uppsala University.^[2][3]

Budd's research focuses on the Cambrian explosion and on the evolution and development, anatomy, and patterns of diversification of the Ecdysozoa, a group of animals that include arthropods.^[1]

Budd was born on 7 September 1968 in Colchester (Essex). He obtained his undergraduate degree at the University of Cambridge and remained there, in the Department of Earth Sciences, to continue his studies at a doctoral level by investigating the Sirius Passet fossil lagerstätte from the Cambrian of North Greenland.^[1] He finished his doctorate in 1994, with one of the findings being a new species of lobopodian, Kerygmachela.^[4] Budd then moved to Sweden as a postdoc along with his PhD supervisor John Peel.^[1]

Together with Sören Jensen he reintroduced the concepts of stem and crown groups to phylogenetics^[5] and is a major critic of molecular clocks current usage in determining the origin of animal and plant groups.^[6][7]

He has edited Acta Zoologica together with Lennart Olsson; he has also edited the Geological Magazine.
