{{short description|Gives a functional equation satisfied by the generating function of any rational cone}}
In [[combinatorics|combinatorial]] [[mathematics]], '''Stanley's reciprocity theorem''', named after [[MIT]] mathematician [[Richard P. Stanley]], states that a certain [[functional equation]] is satisfied by the [[generating function]] of any rational cone (defined below) and the generating function of the cone's interior.
