中央湾（拉丁语为Sinus Medii）是位于月球赤道和本初子午线交点处的一个小型月海。从地球上看来，它位于月球近地面的中央，因此而得名。该地区是月球上距离地球最近的点，从这里看地球总是位于头顶（由于天秤动可能稍有偏差）。该月海的拉丁名字由Johannes Mädler命名，其月面坐标为2°24′N 1°42′E / 2.4°N 1.7°E，直径为335 千米。
中央湾的西部是岛海，北部是汽海，东部则是一片显著的月谷区域。中央湾的东北部横跨着海金努斯月溪，海金努斯环形山正好把这条月溪拦腰截断。东部更远的地方是220千米长的阿丽阿黛月溪，再往东部去，就是静海了。以奥地利天文学家Triesnecker名字命名的Triesnecker月溪在本初子午线上穿过，其西边则是Triesnecker环形山。
中央湾的北部边界由一个多山区域组成，Murchison环形山和Pallas环形山是其中较显著的特征。中央湾中接近北部边界的地方坐落着Chladni环形山。
Another highland region lies to the south and southeastern edge of the Sinus Medii. Several flooded craters lie along this border, with Flammarion near the western edge, then Oppolzer, Réaumur, and Seeliger further east. The Rima Flammarion and Rima Oppolzer rilles lie along the edge of the mare near their corresponding craters. Also along the southeast border and bisecting the prime meridian is the crater Rhaeticus.
In the western half of the interior are the small craters Bruce and Blagg. To the west-southwest of Bruce on the mare floor are the landing sites of the Surveyor 4 and Surveyor 6 missions. Near the western end of the mare are the flooded craters Schröter and Sömmering.
