The Port of Beirut is the main port in Lebanon on the eastern part of the Saint George Bay on Beirut's northern Mediterranean coast, west of the Beirut River. It is one of the largest and busiest ports on the Eastern Mediterranean.

The Beirut River is a river in Lebanon separating the city of Beirut from its eastern suburbs, primarily Bourj Hammoud and Sin el Fil. The river flows mostly east to west from snow drains and springs on the western slopes of Mount Kneisseh and the southern end of Mount Sannine near the towns of Hammana and Falougha, before curving north and emptying at Beirut's northern Mediterranean coast, east of the Port of Beirut. According to popular legend, St. George slew the dragon in a spot near the mouth of the river.
