Kurt Krenn (28 June 1936 – 25 January 2014) was an Austrian Roman Catholic prelate and Bishop who ran a seminary for priests in Sankt Pölten, near Vienna. He was Bishop of the Diocese of Sankt Pölten, a suffragan see of the Vienna province, from 1991 to 2004.
Krenn 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 will not easily allow for the political unity with the Christian faith. He was known for his anti-European Union views.
Krenn resigned from his post in 2004 after the discovery of pornography, including child pornography, at the seminary.
