Oscaecilia zweifeli is a species of caecilian in the family Caeciliidae. It is a poorly known species only known from few specimens: the holotype from the imprecise type locality, "a small creek tributary to Río Mazaruni" in Guyana, one from similarly imprecise Cayenne in French Guiana, and another one from the Nouragues research station in French Guiana. The specific name zweifeli honors Richard G. Zweifel, an American herpetologist. Common names Zweifel's caecilian and tributary caecilian have been coined for it.
