Ludwig I of Württemberg (c. 1098 – 1158) was Count of Wirtemberg. He reigned from 1143 until 1158.
Ludwig I is supposed to be the son of Konrad II and his wife Hadelwig. Together with his brother Emicho he appears from 1134 till 1154 respective 1139 till 1154 at the court of king Konrad III and emperor Friedrich I, Barbarossa. He presumably was Vogt of the Denkendorf monastery.
