William I the Elder of Hesse-Rotenburg (15 May 1648 Kassel – 20 November 1725 Langenschwalbach) was from 1683 until his death Landgrave of Hesse-Rotenburg. He was a son of Ernest I of Hesse-Rotenburg-Rheinfels and his wife Countess Maria Eleonore of Solms-Lich. William was nicknamed the Elder to distinguish him from his nephew William of Hesse-Wanfried.
