Nebaj** is a municipal seat in the **Ixil Triangle** of the **Guatemalan Highlands** (Department of Quiché).
Nebaj is in the **Cuchumatanes Range** (highest non-volcanic mountains in Central America). The **Pacific slope** drains via **Río Samalá, Río Sis, Río Ocosito**. The **Chixoy (Negro) River** drains north from Nebaj to **Usumacinta / Gulf of Mexico**—so Nebaj is near the **continental divide**.
The **Pacific coastal plain (Bocacosta)** is **hot, humid, agricultural** (sugarcane, coffee, rubber, palm). **Retalhuleu** is the nearest major Pacific town; **Champerico** / **Sipacate** are port/beach areas.
