Izabal is one of the 22 departments of Guatemala. Its coastal areas form part of the homeland of the Garifuna people.
Izabal is bordered to the north by Belize, to the north east by the Gulf of Honduras, and to the east by Honduras, and by the Guatemalan departments of Petén to the north west, Alta Verapaz to the west, and Zacapa to the south.
The Izabal Department surrounds Lake Izabal, Guatemala's largest lake. The Spanish Colonial fort of San Felipe, now a Guatemalan national monument, overlooks the point where the lake flows into the Río Dulce.
The small town of Izabal is on the south shore of the lake; before the construction of the ports of Livingston and Puerto Barrios in the 19th century this was Guatemala's main Caribbean Sea port and was the original seat of Izabal department; nowadays, however, Izabal town is a remote village that gets little traffic.
From the area around Lake Izabal, the Department of Izabal stretches along the Río Dulce to the coast of the Caribbean Sea.
The department of Izabal includes the ports of Puerto Barrios, Santo Tomás de Castilla, Livingston and Guatemala's free trade zone Zolic. Izabal also includes the Pre-Columbian Maya ruins of Quirigua.
