Edward Alexander Newell Arber (5 August 1870, London – 14 June 1918, Cambridge) was an English botanist and paleontologist.

Sent to Davos in Switzerland at the age of 15 for health reasons he developed an interest in botany.

Returning home he studied Botany and Geology at Trinity College, Cambridge (1895-1899), where he later became a professor, specialising in palaeobotany.

From 1899 until the end of his life he was appointed demonstrator in Palaeobotany in the Woodwardian [later Sedgwick] Museum in Cambridge.

Between 1901 and 1906 he worked on the naming and arrangement of the palaeobotanical specimens in the Geology Department of the British Museum.
