Konrad IV the Elder (Polish: Konrad IV Starszy, German: Konrad von Oels) (c. 1384 – 9 August 1447) was Duke of Oels (Oleśnica), Koźle, half of Bytom and half of Ścinawa from 1412 to 1416, sharing rule with his brothers. After 1416, he became the sole ruler of Kąty, Bierutów, Prudnik and Syców. In 1417, he assumed the role of Bishop of Wrocław and also held the title of Duke of Nysa.

The son of Konrad III the Old, Duke of Oleśnica, and his wife Judith, Konrad IV the Elder was the eldest of his siblings. His four younger brothers also shared the name of Konrad, but historians distinguish them primarily by letters and regnal numbers.
