Eduard August von Regel (sometimes Edward von Regel or Edward de Regel or Édouard von Regel), Russian: Эдуард Август Фон Регель; (born 13 August 1815 in Gotha; died 15 April 1892 in St. Petersburg) was a German horticulturalist and botanist. He ended his career serving as the Director of the Russian Imperial Botanical Garden of St. Petersburg. As a result of naturalists and explorers sending back biological collections, Regel was able to describe and name many previously unknown species from frontiers around the world.

History
Regel was the son of the teacher and garrison-preacher Ludwig A. Regel. Already as a child he liked growing fruits and learnt to prune apple trees from a gardener of his grandfather Döring and cultivated the garden of his parents. He visited the Gymnasium at Gotha but left without Abitur
Regel earned a degree  from the University of Bonn.

At 15, Regel began his career as an apprentice at the Royal Garden Limonaia in Gotha in 1830-1833 and in spring 1833 went as an adjunct to the botanical garden in Göttingen. He then worked in the botanical gardens in Bonn (1837-1839) and Berlin (1839-1842). In 1842 he moved to Switzerland to become the head of the Old Botanical Garden, Zürich. During this time he also worked as a lecturer of science. In 1852 he founded the magazine Gartenflora (Garden Flora), in which he described many new species.

In 1855 Regel moved to St. Petersburg, Russia, where he initially worked as a research director and later as senior botanist at the Imperial Botanical Garden. From 1875 until his death he served as the director of the Imperial Botanical Garden. While there, he oversaw the creation of some of the gardens (e.g. the Admiralty garden) and the facility laboratory. He was a founder and vice-president of the Russian Gardening Society and a number of academic journals. In 1875, he became an associate member of the St. Petersburg Academy of Sciences. Volume 111 of Curtis's Botanical Magazine is dedicated to him.

Regel died in St. Petersburg in 1892 and was buried at the Smolenskoe Lutheran Cemetery.

Plants named by him
Regel described and named over 3000 plant species. Many of the plants he named were from the Russian Far East and Asia as Russian Geographical Society expeditions where active in this area during his tenure at the Imperial Botanical Gardens in St. Petersburg.

Plants named for him
In 1843, J. C. Schauer named the genus Regelia in honor of Regel. It is a group of flowering plants in the family Myrtaceae which are endemic to the southwest Australia. In 1854, Planchon named the cestrum species Cestrum regelii after him,  Robert Lynch in 1904 a subsection of Iris and 
Iljinia regelii (Bunge) Korovin ex Iljin is also named in his honour.
