Bogislav IX
duke of Pomerania in Pomerania-Stolp

Bogislav IX (German: Bogislaw IX., Polish: Bogusław IX; 1407/1410 – 7 December 1446), was a duke of Pomerania in Pomerania-Stolp, whose residence was Stargard. In 1439 his first cousin Eric of Pomerania tried in vain to have him recognised as his heir to the Kalmar Union.
Bogislav was the son of Bogislav VIII, Duke of Pomerania, and Sophia of Holstein. On 24 June 1432, in Poznan, he married Maria of Masovia, daughter of Siemowit IV, Duke of Masovia and Alexandra of Lithuania. They had daughters, Sophia, who married Eric II, Duke of Pomerania, and Alexandra, and at least one of unknown name.
During the Polish–Teutonic War (1431–1435), Bogislav opposed the Teutonic Knights and supported the Kingdom of Poland. He was later involved in struggles related to Pomeranian bishops.
Upon his death in 1446, Bogislav IX was succeeded in Pomerania-Stolp by Eric of Pomerania, who ruled as "Erik I".
