Al-Marqab (), or in Najdi vernacular pronunciation as al-Margab, is one of the oldest neighborhoods of Riyadh, Saudi Arabia, located east of al-Dirah and south of Thulaim in the sub-municipality of al-Batüha. It was named after the Margab Fort, which was demolished in 1957. As the neighborhood is bounded by al-Batüha Street to the west, its western strip partially forms part of the al-Batüha commercial area.
The early traces of its existence dates back to 16th century, which nearly corresponds with the final stages of the disintegration of Hajr al-Yamamah that resulted in the succession of several settlements from the former.
