Abstract: The main objective of the present work, as a generalization of derivation, is to give the concept of <i>permuting
n-derivations on partially ordered sets (posets)</i>. Several associated theorems and fondamental properties
involving permuting n-derivations are presented. Moreover, we demonstrate that if $$D$$ is a permuting n-derivation
on poset $$G$$ with the greatest element 1 and the trace $$δ$$, then $$δ(1) = 1$$ if and only if $$δ$$ is an identity on $$G$$. Furthermore,
we discuss the relations among derivations, ideals and fixed sets in posets.
