Shams-ud-Din Shah Mir (r. 1339–1342) was a ruler of Kashmir region in India; and the founder of the Shah Mir dynasty, which is named after him. Shah Mir is believed to have come to Kashmir during the rule of Suhadeva (r. 1301–1320), where he rose to prominence. After the death of Suhadeva and his brother Udayanadeva, Shah Mir established his own kingship, founding the Shah Mir dynasty in 1339, which lasted till 1561.
