Günter Heimbeck (born 23 June 1946 in Gunzenhausen, Germany) is a German–Namibian retired professor of mathematics. His particular research interest is geometry; the Heimbeck Planes are named for him. Heimbeck probably is the first and only Namibian scholar to have a scientific sub-discipline carry his name.^[1]

Heimbeck studied mathematics at University of Würzburg from 1965. He completed his PhD in 1974, and his habilitation in 1981.^[2] He then became lecturer at his alma mater. In 1985 Heimbeck emigrated to South Africa, where he taught at the University of the Witwatersrand in Johannesburg. In 1987 he took up a professorship for mathematics at the University of Namibia. Heimbeck is advisor to the Namibian Ministry of Education.^[3]
