thumb|400px|class=skin-invert-image|Visual comparison of convolution, cross-correlation, and [[autocorrelation. For the operations involving function f, and assuming the height of f is 1.0, the value of the result at 5 different points is indicated by the shaded area below each point. The symmetry of f is the reason f \star g and g*f are identical in this example. ]]

在泛函分析中，捲積（又称疊積（convolution）、褶積或旋積），是透過两个函数 f 和 g 生成第三个函数的一种数学算子，表徵函数 f 与经过翻转和平移的 g 的乘積函數所圍成的曲邊梯形的面積。如果将参加卷积的一个函数看作区间的指示函数，卷积还可以被看作是“滑動平均”的推廣。
