Sursock is a Greek Orthodox, Lebanese family and one of Beirut's aristocratic families, along with the Bustros, Dagher, Ferneini, Debbas, and Trad families. The Sursock family made their money as traders. The Sursocks were also landowners and for many decades Lebanon's leading business family, joining forces with the Otis Elevator Company to manufacture elevators.Rue Sursock in the Achrafieh district in Beirut is named after the family, which owned many palatial homes on the street, such as the Sursock House.

The Sursock family financed the building of the Beirut Hippodrome in 1918.

In addition to owning land in Lebanon, the Sursock family owned more than 60,000 acres (240 km²) in the Vale of Esdraelon, the Jezreel Valley, in Palestine. The land encompassed 13 villages in the Emek. It is believed that the Sursock family sold the land in Palestine for nearly three quarters of a million pound to the Jewish National Fund in 1906. The family evicted the Arab tenants of the villages to allow the Jewish settlers to move in.
