Johann Friedrich Abegg (November 30, 1765 in Roxheim near Kreuznach – December 16, 1840 in Heidelberg) was a German theologian. He was the brother of many siblings in a family of preachers, and was adopted in 1786 as candidate for the preacher office in the Electorate of the Palatinate. He visited the college in Heidelberg from 1789 to 1794 and also worked as extraordinary professor of philology since 1791. In 1794 he started to practise as priest, first in Boxberg, then in Leimen (1799) and Heidelberg (1808) in the parishes St. Peter and Heiliggeist.
