Kurt Krenn (28 June 1936 – 25 January 2014) was an Austrian Roman Catholic prelate and Bishop of Sankt Pölten, near Vienna, from 1991 to 2004.

He earned licentiate degrees in theology and canon law, as well as a doctorate in philosophy with a dissertation on "The Meaning of Being in the Condition of Participation" in Thomas Aquinas.

After studying in Tübingen (1966-1967) and Munich (1967-1970), where he was an assistant to Wilhelm Keilbach at the theological faculty, he was professor of philosophy at the Philosophical-Theological Institute at Linz from 1970 to 1975.

He argued against Turkey's entrance into the European Union, warning against the 'Islamisation' of Europe and calling Islam a "very aggressive kind of religion" that would not easily allow for the political unity Christian neighbors.

On 29 September 2004 Krenn resigned from his episcopate at the request of Pope John Paul II, though without confirming the accusations.
