卡累利阿地峡（俄语：Карельский перешеек、芬兰语：Karjalankannas）是连接斯堪的纳维亚半岛与欧亚大陆的峡地，地峡两边为芬兰湾和拉多加湖。

1929年芬兰开始修建横跨地峡的曼诺海姆防线。1939年苏芬战争在这里进行。战争之后，芬兰政府将包括地峡在内的共约10%的领土割让给苏联。二战期间，芬兰与苏联在这里进行了战斗。

The Karelian Isthmus (Russian:Карельский перешеек; Finnish:Karjalankannas) is the approximately 45–110 km wide stretch of land, situated between the Gulf of Finland and Lake Ladoga in northwestern Russia, to the north of the River Neva (between 61°21’N, 59°46’N and 27°42’E, 31°08’E). Its northwestern boundary is the relatively narrow area between the Bay of Vyborg and Lake Ladoga. If the Karelian Isthmus is defined as the entire territory of present-day Saint Petersburg and Leningrad Oblast to the north of the Neva, the isthmus' area covers about 15,000 km.
