巨花魔芋，（学名：Amorphophallus titanum），又名尸花、泰坦魔芋，是天南星科魔芋属植物。

巨花魔芋具有世界上最大的不分支花序；世界上最大的分枝花序，则是贝叶棕的花序；世界上最大的花则为大花草的花。巨花魔芋的印尼文名称叫做「bunga bangkai」，「bunga」意为「花」，「bangkai」意为「尸体」，巨花魔芋在开花的时候会散发一股类似尸臭的味道，因此又有「尸花」的别名。在印尼，同样的名称也用来称呼大花草，因为大花草开花时也会散发类似的气味。大花草和巨花魔芋一样，原生地都为印尼的苏门答腊热带雨林。

Amorphophallus titanum (from Ancient Greek amorphos, "without form, misshapen" + phallos, "phallus", and titan, "giant"), known as the titan arum, is a flowering plant with the largest unbranched inflorescence in the world. The titan arum's inflorescence is not as large as that of the talipot palm, Corypha umbraculifera, but the inflorescence of the talipot palm is branched rather than unbranched.
