Samuel Dickenson (1733 – May 15, 1823) was a clergyman and botanist.
He was educated at St John's College, Cambridge, where he was a contemporary of Erasmus Darwin. He succeeded his father John Dickenson as Rector of St. Mary's, Blymhill and remained in the position from 9 January 1777 until his death, aged 90, in 1823.
Dickenson contributed to various botanical and historical works and was tutor to Thomas Beddoes and Charles Darwin (uncle of the famous naturalist Charles Robert Darwin). He accompanied the 8 year old Darwin on an excursion to France, collecting plants, between October 1766 and March 1767.
