Alfred Reginald Pryor (24 April 1839 – 18 February 1881) was an English botanist.
He was born there on 24 April 1839, and received his early education at Tunbridge school, whence he went to University College, Oxford, graduating B.A.
He soon grew interested in botany, and projected a new flora of his native county, which formed the main occupation of the remainder of his life.
He was compelled by bad health to winter abroad, 1879–1880, and he died unmarried at Baldock on 18 February 1881.
His detached papers, showing great critical knowledge of plants, for the most part came out in the ‘Journal of Botany,’ 1873–81.
