阿卡湖是瑞典的水库，位于该国北部北博滕省，长60公里、宽5公里，面积266平方公里，海拔高度453米，平均水深30米，最大水深92米，蓄水量4.65亿立方米。

Akkajaure (from lule sami Áhkájávrre) is one of the largest reservoirs in Sweden. It lies at the headwaters of the Lule River in Norrbotten County, in Swedish Lappland, within the Stora Sjöfallet national park. The lake formed after the construction of the first Suorva dam in 1913–1923. The rim of the current dam is at an elevation of 453 m (1,486 ft). When full, the lake's maximum depth is 92 m (302 ft), and its mean depth is about 30 m (98 ft). Because it is used for power generation, the lake depth fluctuates by up to 30 m (98 ft).
