George Henslow (23 March 1835, Cambridge, UK – 30 December 1925, Bournemouth) was an Anglican curate, botanist and author.

He was a prolific author and speaker on botanical subjects; the separates from current publications between 1871–1915 occupy eleven bound volumes in the Linnean Library, indexed in his own hand, and interleaved with interesting MS letters from his correspondents.

George Henslow believed in the inheritance of acquired characters in plants, and combated the newly recognised work of August Weismann.

[6] Henslow was a proponent of theistic evolution who held that "natural selection plays no part in the origin of species.

"[7] He promoted his Lamarckian theory of evolution in plants by direct adaptation, known as "the True Darwinism".
