拉森冰架（英语：Larsen Ice Shelf）是位于南极半岛边缘、威德尔海西北方的冰架，从南极半岛东岸的渴望角延伸至赫斯特岛南方。名称是以挪威捕鲸船「杰森」号船主卡尔·安东·拉森命名，他于1893年12月驾船抵达了南纬68°10'的冰棚前缘。

拉森冰架可再被细分为3块不同的冰棚区域，从北到南依序是：拉森A、拉森B、拉森C。其中拉森A面积最小，且已于1995年1月崩解消失。拉森B则于2008年崩解。拉森C在2008年趋于稳定，但科学家预测以当地的暖化速率来看，在可预见的未来内，拉森C也会崩解消失。

The Larsen Ice Shelf is a long, fringing ice shelf in the northwest part of the Weddell Sea, extending along the east coast of Antarctic Peninsula from Cape Longing to the area just southward of Hearst Island. Named for Captain Carl Anton Larsen, the master of the Norwegian whaling vessel Jason, who sailed along the ice front as far as 68°10' South during December 1893. In finer detail, the Larsen Ice Shelf is a series of three shelves that occupy (or occupied) distinct embayments along the coast. From north to south, the three segments are called Larsen A (the smallest), Larsen B, and Larsen C (the largest) by researchers who work in the area.
