Georg Kükenthal (30 March 1864 in Weißenfels – 20 October 1955 in Coburg) was a German pastor and botanist who specialized in the field of caricology.
In his 1909 monograph, he divided the genus Carex into four subgenera: Primocarex, Vignea, Indocarex and Eucarex.
Carex is the largest monophyletic (natural) genus of flowering plants; Kükenthal's monograph remains the only comprehensive, worldwide treatment.
On 8 July 1920 he was finally elected as the last General Superintendent and thus the highest clergyman of the independent regional church of Coburg.
After the Coburg regional church joined the Bavarian regional church on 1 April 1921, Kükenthal was head of the Evangelical Lutheran deanery of Coburg until his retirement on 1 July 1928.
