Mare Marginis (Gränshavet) är ett litet månhav på månens norra halvklot, på den östra del av månen som på grund av librationen inte alltid kan observeras från jorden. Det är oregelbundet format och snarast avlångt i väst-östlig riktning. Det ligger norr om månhavet Mare Smythii, mellan dessa månhav ligger kratrarna Neper och Jansky. I Mare Marginis norra del ligger kratern Goddard och norröver ligger kratrarna Hubble och Joliot.

en:Mare Marginis lies on the very edge of the lunar nearside. It differs from most of the nearside maria. It has an irregular outline, and it appears to be fairly thin. Note the small circular and elongated features in the mare plains. These probably mark impact craters buried by less than 1000 - 1700 feet of lava. Further, Mare Marginis is not centered on any clear, large impact basin. Thus, Mare Marginis seems to mark a low-lying region of the highlands where mare lavas were just able to reach the surface. Several large mare-floored craters also occur nearby. In these craters, the crater floors lie below the surrounding highland surface. Thus, they mark sites around Mare Marginis where lavas were close to the lunar surface. The major crater to the north of Marginis Al-Biruni, with Ibn Yunus to the southeast, and Goddard to the northwest.
