喀拉海（俄语：Карское море，英语：Kara Sea）位于俄罗斯西伯利亚以北，是北冰洋的一部分。在西边，新地岛和喀拉海峡将喀拉海与巴伦支海隔开，在东边，北地群岛又将喀拉海与拉普捷夫海分离。

喀拉海长约1,450公里，宽约970公里，水域面积880,000平方公里，平均水深110米。注入喀拉海的河流有鄂毕河、叶尼塞河和皮亚西纳河。其沿岸的主要城市是诺维港和迪金森。喀拉海是重要的渔场，并已勘探出石油和天然气。

喀拉海曾是苏联倾倒核废料的地方，共计有六艘核动力潜艇反应堆和十个核反应堆在该海域中。一份国际原子能机构的报告显示，此地的核幅射较低并处于较小的范围之内。

The Kara Sea (Russian:Ка́рское мо́ре, Karskoe More) is part of the Arctic Ocean north of Siberia. It is separated from the Barents Sea to the west by the Kara Strait and Novaya Zemlya, and the Laptev Sea to the east by the Severnaya Zemlya archipelago. It is named for the Kara River (flowing into Baydaratskaya Bay), which is now relatively insignificant but which played an important role in the Russian conquest of northern Siberia. The word "kara" is derived from kara, which in several Turkic languages means "black" and also symbolizes "north".
