Frederick IV, Count of Leiningen

Frederick IV (c. 1250–1316) was Count of Leiningen, son of Count Frederick III and Adelaide of Kyburg. He ruled the family lands jointly with his uncle Emicho IV and cousin Emicho V, and after Emicho V died around 1289 he inherited part of their estates, including Madenburg Castle.

From 1275 to 1301 he was landvogt of Speyergau under Emperor Rudolf of Habsburg, and in 1301 Emperor Albert I pledged him Falkenburg Castle. His sons Frederick V of Leiningen-Dagsburg and Godfrey of Leiningen-Hardenburg divided the inheritance in 1317.
