Ernst Rudolf Huber (8 June 1903 – 28 October 1990) was a German jurist, noted as a constitutional historian and for his attempts to provide a legal underpinning for the Nazi regime. Huber studied law in Bonn under Carl Schmitt. He received a PhD in 1926 for a work on state church law, and his habilitation in 1931 for a work on economic administrative law, which he was instrumental in establishing as a field of study. In 1933, he was called to teach in Kiel, and subsequently also taught law in Leipzig after 1937 and in Strasbourg from 1941 to 1944.
