柯布-道格拉斯生产函数（英语：Cobb–Douglas production function），又称Cobb–Douglas函数（Cobb–Douglas function），是个体经济学上用来描述生产函数的常用函数之一。此函数最早由努特·维克塞尔（Knut Wicksell）提出，于1900年至1928年间经过Charles Cobb和Paul Douglas的统计验证后确立，并因而得名。

In economics, the Cobb–Douglas production function is a particular functional form of the production function, widely used to represent the technological relationship between the amounts of two or more inputs, particularly physical capital and labor, and the amount of output that can be produced by those inputs. Sometimes the term has a more restricted meaning, requiring that the function display constant returns to scale (in which case in the formula below). The Cobb-Douglas form was developed and tested against statistical evidence by Charles Cobb and Paul Douglas during 1927–1947.
