Lord Richard Percy (11 February 1921 – 23 December 1989) was an English zoologist with an aristocratic and military background, best known for his specialist research on lampreys. He had a long association with Newcastle University and the field of Northumbrian natural history. Having published some work in East Africa in the early 1950s, he also undertook research on behalf of the U.K. government into the ecology of seabirds in the Seychelles.
