Mareeg (also known as Mareg, Meregh and Märēg) is a locality in the Galguduud region of central Somalia, in the Galmudug state.

In 1891, the religious figure Sheikh Daud Culusow, a Waceysle Abgaal Imam, established the modern town of Mareeg and a principality that also encompassed Ceel Buur, Masagaway, Xarardheere,[3] alongside his two disciples; Xaaji Cumar Muudey and Macallin Cusman Kulmiye, also of the Waceysle subclan.

Sheikh Cumar Muudey served as the judge of the town, and Macalin Cusman led the Quranic school.

The principality was under threat from the European Colonial project of Yusuf Ali Kenadid's dynasty in Hobyo and the Dervish movement forces coming from Beledweyne (named Bulo Macanne at the time).

According to the catalogo of the Museo della Garesa, coins from an early historical epoch were also recovered in the town.
