亚速海（乌克兰语：Азовське море；俄语：Азовское море；克里米亚鞑靼语：Azaq deñizi）是一个陆间海：西面有克里米亚半岛，北面为乌克兰而东面为俄罗斯。只有刻赤海峡与黑海相连。

长349公里、阔135公里，面积37,555平方公里。主要的河流有顿河和库班河：这降低了海水的盐度和带来了沉积物。事实上，它是世界上最浅的海，平均深度只有13米，最深处仅15.3米，在塔甘罗格湾（Taganrog），水深甚至不足1米，西面有长达110公里名为阿拉巴特岬的沙洲和锡瓦什湖。

亚速海海流以逆时针方向运动，潮水高度不定，但最高可达5公尺。冬季大幅封冻。根据黑海沉降理论，形成于前5600年。在水下有新石器时代遗迹。古代希腊语和拉丁语分别称为“ἡ Μαιῶτης λίμνη”和“Palus Maeotis”。

The Sea of Azov (Russian:Азо́вское мо́ре, tr.Azovskoye more; Ukrainian:Азо́вське мо́ре, Azovs'ke more; Crimean Tatar:Azaq deñizi) is a sea in south-eastern Europe. To the south it is linked by the narrow (about 4 km or 2.5 mi) Strait of Kerch to the Black Sea, and it is sometimes regarded as a northern extension of the Black Sea. The sea is bounded in the north by mainland Ukraine, in the east by Russia, and in the west by the Crimean Peninsula. The Don and Kuban are the major rivers that flow into it. The Sea of Azov is the shallowest sea in the world, with the depth varying between 0.9 and 14 meters (2 ft 11 in and 45 ft 11 in). There is a constant outflow of water from the Sea of Azov to the Black Sea.
