Suleiman Nabulsi was a leftist Jordanian political figure who served as Prime Minister of Jordan in 1956–57.
In October 1956 during the 1956 elections, the National Socialist Party headed by Nabulsi won a plurality of 16 out of 40 seats in the Jordanian House of Representatives. Subsequently, King Hussein asked him to form a government; it was the only elected government in Jordan's history.
Nabulsi's government was short-lived. His policies as Prime Minister frequently clashed with that of King Hussein's. Nabulsi wanted Jordan to move closer to Egypt under Gamal Abdel Nasser, but Hussein wanted it to stay in the Western camp. Disagreements between the monarchy and the leftist government culminated after Nabulsi provided Hussein with an expanded list of officers in the army he wanted to dismiss. Nabulsi was forced to resign in March 1957.
