Senâm is the name of a long, low hill situated in M'sila Province, Algeria, southwest of Algiers. The hill is covered with a large number of stone circles.
These stone circles are built of natural limestone, with standing slabs high. The diameter of the circles varies between about and . The entrance to the circles is on the southeastern side of the hill, through a larger, surrounding circle. It is uncertain if the niche was once roofed. The center of the circle is filled with stones for unknown purposes, possibly as a grave.
