Richard Lynn (born 1930) is a British Professor Emeritus of Psychology who is known for his views on racial and ethnic differences. Lynn says that there are race and sex differences in intelligence.

Lynn was educated at Cambridge University. He has worked as lecturer in psychology at the University of Exeter, and as professor of psychology at the Economic and Social Research Institute, Dublin, and at the University of Ulster at Coleraine. He has written or co-written more than 11 books and 200 journal articles spanning five decades. Two of his recent books are on dysgenics and eugenics.

In the late 1970s, Lynn wrote that he found a higher average IQ in East Asians compared to Whites (5 points higher in his meta-analysis). In 1990, he proposed that the Flynn effect – an observed year-on-year rise in IQ scores around the world – could possibly be explained by improved nutrition, especially in early childhood.
