Al Majma'ah (Arabic: المجمعة) is a city and a governorate in Riyadh Province, Saudi Arabia.

Founded in 1417 CE by an immigrant from the Alshammari tribe, Al-Majma'ah was historically considered the capital of the region of Sudair.

Al Majma'ah is an important stop along the North-South line, which is operated by The Saudi Arabia Railways.

This railway line links the city to major destinations such as Riyadh, Al-Qassim, Ḥaʼil, Al-Jawf, and Qurayyat, enhancing transportation and connectivity across the region.

Al-Fayha and Al-Faisaly are particularly renowned for their strong home performances and have gained a reputation for being tough opponents to top teams in the Saudi Pro League.
