Sir Cyril Lodowic Burt (3 March 1883 – 10 October 1971) was an English educational psychologist who made contributions to educational psychology and statistics.

Burt is known for his studies on the heritability of IQ. Shortly after he died, his studies of inheritance and intelligence came into disrepute after evidence emerged indicating he had falsified research data. Some scholars have asserted that Burt did not commit fraud.
