This region occupies 34.7% of Qatar's total area, south of Doha's latitude. It bears topographical similitude to the desert areas of [[Abu Dhabi]], [[Saudi Arabia]], and [[Bahrain]], with undulating sand dunes interspersed with rocky [[hamada]] surfaces.<ref name="qencyclopedia"/> It is divided into four sub-regions:
#Al Urayq: A triangular area in the extreme west, with its apex at Abu Samra. Its northern side aligns with the southern extremity of the Doha-Abu Samra road, and its southern side follows the border line from Abu Samra towards the southeast.<ref name="qencyclopedia"/>
#Miocene-Tiwar: Characterized by isolated hills amidst a rocky plain. The hills reach a maximum of {{convert|103|m}} and include Qatar's highest point, [[Qurayn Abu al Bawl]]. This sub-region is concentrated in the southwestern part of the Qatar Peninsula, including areas like [[Mukaynis]], [[Al Kharrara]], and [[Wadi Jallal]].<ref name="qencyclopedia"/>
#Rocky surfaces: Consisting of expanses of exposed bedrock, often weathered into flat, stony plains known as desert pavements. The surface may be covered by a mosaic of closely packed pebbles and rock fragments, or in some places by a thin layer of indurated mineral deposits forming a hard crust. This sub-region is divided into two units: one shaped like a trapezoid bounded by the water pipeline passing through [[Abu Nakhla]] to Mesaieed, and another extending from Umm Jawlaq southeastward through Al Khubayb, Al Fulayhah, and Umm Al Hayran to Khor Al Adaid.<ref name="qencyclopedia"/>
#Sand dunes: Occupying 1.6% of Qatar's area, with dunes reaching heights of {{convert|38|m}} to {{convert|67|m}}. Interspersed among the dunes are numerous closed basins with floors varying in elevation from {{convert|19|m}} to {{convert|34|m}} metres above sea level, resulting in an undulating topography. The northern boundary of this sub-region aligns with the latitude of Umm Owaina.<ref name="qencyclopedia"/>
