Graham Edward Budd is a British palaeontologist. He is Professor and head of palaeobiology at Uppsala University.

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.

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. He finished his doctorate in 1994, with one of the findings being a new species of lobopodian, Kerygmachela. Budd then moved to Sweden as a postdoc along with his PhD supervisor John Peel.

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

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