Joseph Gottlieb Kölreuter (April 27, 1733 – November 11, 1806), also spelled Koelreuter or Kohlreuter, was a German botanist.

Kölreuter was born the son of a pharmacist in Karlsruhe, Germany, and grew up in Sulz. He studied medicine at the University of Tübingen under physician and botanist Johann Georg Gmelin, receiving his PhD in 1755.

He worked in St. Petersburg from 1756 to 1761, when he moved back to Sulz and in 1762 to Calw.

Kölreuter described many plant species, and studied pollen. He was the first scientist to hybridize plants for scientific purposes, specifically the tobacco plants Nicotiana rustica and Nicotiana paniculata.[1]

The genus Koelreuteria has been named in his honour.

Kölreuter died in Karlsruhe, Germany.
