Johann Ladislaus Pyrker (von Oberwart) (von Felsö-Eör) (Hungarian: felsőőri Pyrker János László, born at Nagyláng, Soponya, near Székesfehérvár, Hungary, 2 November 1772; died at Vienna, 2 December 1847) was a Hungarian Cistercian abbot, archbishop and poet.
He was descended from an old Hungarian noble family. His father was one of the eighteen hussars who distinguished themselves in the battle of Kunersdorf.
Graduated from Székesfehérvár and Pécs, he applied for a civil service position in Buda but was unsuccessful. In 1792 he entered the Cistercian chapter house at Lilienfeld Abbey, where he was ordained priest (1796). In quick succession he was steward, chancellor, prior, abbot, for a time, parish priest at Türnitz, and brought the monastery to prosperity.
He was appointed Bishop of Spiš (1818), Patriarch of Venice and Primate of Dalmatia with his see in Venice (1820), and finally Archbishop of Eger (1827). He founded health resorts in Karlovy Vary and Gastein for sick soldiers, a seminary for country school teachers at Eger, and donated 10,000 early florins toward the adornment of Eger Cathedral. His collection of paintings forms the basis of the Hungarian National Museum. For these charitable gifts he was knighted by the emperor with the title of Felsö-Eör. In 1827 he was founded a string quartet in Eger by his noble music instruments, one of these the 1697's Stradivari's violin, named Cecilia, newly discovered in 2011. He was known to the composer Franz Schubert who set two songs to his texts: D851 Das Heimweh and D852 Die Allmacht. Pyrker let it be known that he liked Schubert's D489 Der Wanderer, and was duly obliged with the dedication of Schubert's Opus 4.
