Abstract. In this paper, we construct a groupoid associated to a module with values in the space of all derivations of a unital algebra. More precisely, for a pair (A; G) consisting of an algebra A with a unit, a module G over the center Z(A) of A together with a homomorphism of Z(A)-modules from G to the space of all derivations Der(A) of A; we associate a groupoid. We discuss on the equivalence relation induced from this groupoid.
