Lambertus de Monte, also Lambertus de Monte Domini or Lambert of Cologne (Dutch; Flemish: Lambertus van 's-Heerenbergh; c. 1430/5 - 1499), was a medieval scholastic and Thomist.
Originally from 's-Heerenberg (Monte Domini), he went to the University of Cologne in 1450, where he was taught by his uncle Gerhardus de Monte, and received his Master of Arts in 1454, holding an arts professorship there from 1455 until 1473, when he became a doctor of theology. He then taught in the faculty of theology until his death.
He wrote several Thomist commentaries on Aristotle, including the Physics, De anima, and the logica nova, most of which were printed in Cologne during his lifetime or shortly thereafter. He was a defender of the Thomistic interpretation of Aristotle against that of Albert the Great and his followers. He was a member of the Schola Coloniensis of Thomists. Notably, he argued for Aristotle's salvation against the scholarly consensus that Aristotle was in Hell. He also wrote copulata (introductory logical analysis) of Peter of Spain. Besides Thomas and Gerhardus, he was influenced by Henry of Gorkum, Gerhardus' teacher. After Henry and Gerhardus, he was the third doctor of the bursa Montana, a college of students and faculty living in common.
