Georg Christian Crollius (21 July 1728 – 23 March 1790) was a German historian and librarian.
He was born in Zweibrücken, the son of the gymnasial headmaster Johann Philipp Crollius and Margaretha Gabriela Joannis.
He succeeded his father in the management of the Herzog-Wolfgang-Gymnasium in Zweibrücken, the most renowned school in Palatinate-Zweibrücken.
Duke Christian IV appointed him also to the committee of the library, the present-day Bibliotheca Bipontina, and to court historiographer.
Similar to his father he researched the history of Palatinate-Zweibrücken and of the Rhenish County Palatine.
