Tartus comprises roughly half of Syria's Mediterranean coastline; offshore lie five small islands, the largest of which is Arwad. Inland the terrain is mountainous, comprising a section of the Syrian Coastal Mountain Range (Nusayriyah Mountains). The Nahr al-Kabir river forms the border with Lebanon to the south.

Tartus is the regional capital; other major settlements include Al-Hamidiyah, Al Qadmus, Al-Sawda, Ayn ash Shams, Baniyas, Qusaybah and Safita.

The governorate is divided into five districts (manatiq). The districts are further divided into 27 sub-districts (nawahi):

As per the 2004 Syrian census the population was 701,400. A 2011 UNOCHA estimate put the population at 797,000, though this has likely changed since the start of the war.

The majority at 72% are Alawites, 7% Sunni Muslim, 8% Ismaili, and 13% Christian. There is a small Cretan Greek community concentrated in Al-Hamidiyah, the descendants of refugees who fled the Greco-Turkish War of 1897.
