Alois Karl Hudal (also known as Luigi Hudal; 31 May 1885 – 13 May 1963) was an Austrian bishop of the Catholic Church, based in Rome. For thirty years, he was the head of the Austrian-German congregation of Santa Maria dell'Anima in Rome and, until 1937, an influential representative of the Catholic Church in Austria.

In his 1937 book, The Foundations of National Socialism, Hudal praised Adolf Hitler, and his policies and indirectly attacked Vatican policies. After World War II, Hudal helped establish the Ratlines, which allowed prominent Nazi German and other European former Axis officers and political leaders, among them accused war criminals, to escape Allied trials and denazification.
