鲸落（Whale Fall），指鲸死去后沉入海底的现象。当鲸在海洋中死去，它的尸体最终会沉入海底，生物学家赋予这个过程以鲸落的名字。一座鲸的尸体可以供养一套以分解者为主的循环系统长达百年。鲸落是指鲸鱼死亡后落入深海形成的生态系统，与热液、冷泉一同被称为是深海生命的“绿洲”。在北太平洋深海中，鲸落维持了至少有43个种类12490个生物体的生存，促进了深海生命的繁荣。
Whale fall refers to phenomenon that whales sink to the bottom of the sea after they a whale dies in the ocean，its body eventually sinks to the bottoms of the sea，a process biologists call whale landing.
