通气管（英语：snorkel）是指使用在潜艇的通气设备。

通气管第一次大量装备使用是在二战时期。当时的柴电常规动力潜艇在水下以电池作为动力。需要上浮使用柴油机充电并补充压缩空气和更新潜艇内的空气，但这样会暴露潜艇。使用通气管可以保持在潜望镜深度开动柴油机而不必浮出水面，防止潜艇暴露踪迹。

A submarine snorkel is a device which allows a submarine to operate submerged while still taking in air from above the surface. Royal Navy personnel often refer to it as the snort. A concept devised by Dutch engineers was widely used on German U-boats during the last year of World War II.
