Rudolf Kittel (28 March 1853, in Eningen, Württemberg – 20 October 1929, in Leipzig) was a German Old Testament scholar.
Kittel studied at Tübingen University (1871–76). He was a professor of Old Testament studies at the universities of Breslau (1888–98) and Leipzig (1898–1923). In 1917 he was appointed rector at the University of Leipzig.
He produced commentaries and histories of the Israelites and the Near East, but his most enduring work was his critical edition of the Hebrew scriptures, Biblia Hebraica, which has remained a standard text.
Kittel's son was the theologian and Nazi apologist Gerhard Kittel.
