Christian Körner (born 29 March 1949) is an Austrian–Swiss botanist and emeritus professor at the University of Basel.

He completed his PhD on water relations of alpine plants in 1977 at the University of Innsbruck (supervised by Walter Larcher).

Körner has a widely known talent in explaining complex and seemingly difficult subjects.

This was especially the case when Körner was invited by His Majesty the King of Sweden in 2003 to participate in a private royal colloquium aimed at describing and discussing the problems of global environmental change for the biosphere.

Therefore, he attended the BES Science Slam 2015 in Edinburgh, performing 'What carbon cyclists can learn from bankers'.
