Ludwig Ott (24 October 1906 – 25 October 1985) was a Roman Catholic theologian and medievalist from Bavaria, Germany.
He received his doctorate in Munich (1931-1936) under Martin Grabmann and was mentored by him in studying the development of medieval theology.
In 1936 he was außerordentlicher Professor,[citation needed] and in 1941 an ordentlicher Professor of dogmatics at the episcopal philosophical and theological college in Eichstätt.
With his Fundamentals of Catholic Dogma he produced a standard reference work on dogmatics.
The work, popular with both clergy and laity, has been translated into more than ten languages.
