Patrick Benedict Zimmer (born at Abtsgmund, Württemberg, 22 February 1752; died at Stenheim near Dillingen, 16 October., 1820) was a Catholic philosopher and theologian.
Zimmer studied the Humanities and philosophy at Ellwangen, theology and jurisprudence at Dillingen and was ordained a priest on 1 April 1775.
In 1795 he was dismissed from the faculty of the university, ostensibly because as pastor of Steinheim he should reside at that place, but in reality, because of his extreme idealism.
To lessen the danger of inculcating his philosophical tenets in his lectures, he was relieved of the professorship of positive theology and given that of Biblical archaeology and exegesis in 1807.
His chief theological work, "Theologiae christianae specialis et theoreticae" (4 parts, Landshut, 1802-6), is to a great extent permeated with Schellingian pantheism.
