Which city is Saudi Arabia's most populous?

Riyadh is Saudi Arabia’s most populous city.

Riyadh is the capital of Saudi Arabia and the headquarters of the national government, making it the country’s main political and administrative centre. It is located in the Najd plateau in the interior of the Arabian Peninsula, on the eastern side of Wadi Hanifa. Unlike Jeddah, which is a major Red Sea port, Riyadh is an inland metropolis.

Saudi Arabia’s population is concentrated in several large urban regions, so rankings can vary when sources compare municipal boundaries with metropolitan areas. Nevertheless, Riyadh leads the country under standard city-population comparisons. A 2022 figure for the city is about 7 million residents, with the wider metropolitan area exceeding that total.

The name Riyadh is associated with the Arabic word for gardens or meadows, reflecting the oasis settlements that preceded the modern city. The present metropolis expanded rapidly during the twentieth century, especially after oil wealth, state investment, and road and air connections transformed the former walled town. Mecca and Medina are globally important religious cities, while Jeddah is a major commercial centre, but neither surpasses Riyadh in population.
