Sir Richard John Roberts FRS (born 6 September 1943, Derby) is a British biochemist and molecular biologist.

He was awarded the 1993 Nobel Prize in Physiology or Medicine with Phillip Sharp for "the discovery that genes in eukaryotes are not contiguous strings but contain introns, and that the splicing of messenger RNA to delete those introns can occur in different ways, yielding different proteins from the same DNA sequence".

Roberts has worked at Harvard University, Cold Spring Harbor Laboratory and New England Biolab. He was knighted in the 2008 Birthday Honours.
