Ivan Sansom (born Prestatyn) is a British palaeontologist, Senior Lecturer in Palaeobiology at the University of Birmingham. His research has focused primarily on the conodont palaeobiology and the early Palaeozoic radiation of vertebrates.

Sansom is an editor of the Journal of the Geological Society.

In 2001 Sansom was a recipient of the Palaeontological Association's Hodson Award, conferred on palaeontologists who have made a notable early contribution to the science.
