Deoxycytidine triphosphate deaminase (dCTP deaminase) is an enzyme involved in nucleotide metabolism. It catalyses the formation of dUTP (deoxyuridine (5'-)triphosphate), which in turn is degraded by dUTPase (dUTP diphosphatase) to produce dUMP (deoxyuridine monophosphate). dUMP is the immediate precursor of thymidine nucleotides [PMID: 1324907].

Members of this family include the Escherichia coli monofunctional deoxycytidine triphosphate deaminase (dCTP deaminase) [PMID: 1324907] and a Methanocaldococcus jannaschii (Methanococcus jannaschii) bifunctional dCTP deaminase (EC: diphosphatase (EC: [PMID: 12538648].
