Tilman Pesch (1 February 1836, at Cologne – 18 October 1899, at Valkenburg, Limburg, the Netherlands), was a German Jesuit philosopher.
From 1870 to 1876 he worked in the ministry, and again taught philosophy eight years (1876–84), at the Castle of Bleijenbeek in Afferden.
His Latin writing contain the latest results of natural science applied to the illustration of truth by scholastic methods.
The most important of these were the articles published in the "Germanica" above the pseudonym "Gottlieb"; they were later arranged in three volumes, Briefe aus Hamburg (1883), Der Krach von Wittenburg (1889), and Wittenberg und Rom (1889), arguing against common criticisms of the Catholic Church.
