数学上，微分拓扑的外微分算子，把一个函数的微分的概念推广到更高阶的微分形式的微分。它在流形上的积分理论中极为重要，并且是德拉姆和Alexander-Spanier上同调中所使用的微分算子。其现代形式是由嘉当发明的。

On a differentiable manifold, the exterior derivative extends the concept of the differential of a function to differential forms of higher degree. The exterior derivative was first described in its current form by Élie Cartan in 1899; it allows for a natural, metric-independent generalization of Stokes' theorem, Gauss's theorem, and Green's theorem from vector calculus.
