In this paper we give an abstract coincidence point result with respect to which some results such as of Peetre-Rus (I.A. Rus, Teoria punctului fix în analiza funcțională, Babeș-Bolyai Univ., Cluj-Napoca, 1973), A. Buică (A. Buică, Principii de coincidență și aplicații, Presa Univ. Clujeană, Cluj-Napoca, 2001) and A.V. Arutyunov (A.V. Arutyunov, Covering mappings in metric spaces and fixed points, Dokl. Math., 76(2007), no.2, 665-668) appear as corollaries. In the case of multivalued mappings our result generalizes some results given by A.V. Arutyunov and by A. Petrușel (A. Petrușel, A generalization of Peetre-Rus theorem, Studia Univ. Babeș-Bolyai Math., 35(1990), 81-85). The impact on metric fixed point theory is also studied.
