Alois Josef, Freiherr von Schrenk und Nötzig (Czech: Aloys Josef svobodný pán Schrenk z Notzing) (24 March 1802 – 5 March 1849) was the Roman Catholic archbishop of Prague from 1838 to 1849.

Schrenk invited the French congregation of the Sisters of Mercy of St. Borromeo to Prague.

The Prague community was confirmed as a separate congregation in 1841 and soon became one of the most numerous and most significant orders in Bohemia.

On 22 March he issued a censure, as some priests, forgetting their sacred calling, turned the pulpit into a political platform.

His address at the Easter festival, posted on the streets in Czech and German, sought to allay the hostility to the Jewish population ... strain he had undergone shattered the health of the archbishop and he died in March, 1849, at the age of forty-seven.
