Abu Sa'id Taj ad-Dawla Tutush I (Arabic: أبو سعيد تاج الدولة تتش السلجوقي) (died 1095) was the Seljuq ruler (probably sultan or emir) of Damascus from 1079 to 1095, succeeding Abaaq al-Khwarazmi. He finished the construction of the Citadel of Damascus, a project that had begun under the direction of Abaaq al Khwarizmi. Tutush took control of Syria in 1085 from his brother, the sultan of the Great Seljuq Empire Malik Shah I, but lost it in 1086, only to recapture it in 1094. After his death in 1095, his younger son Duqaq inherited Damascus, causing Duqaq's older brother Radwan to revolt, splitting their father's realm.
