Ang Cytosine (C) ang isa sa apat na pangunahing mga base na matatagpuan sa DNA at RNA kasama ng adenine, guanine at thymine(uracil sa RNA). Ito ay isang deribatibo ng pyrimidine na may isang heterosiklikong aromatikong singsing at dalawang mga substituente na nakakabit(isang pangkat amine sa posisyong 4 at isang pangkat keto sa posisyong 2). Ang nucleoside ng cytosine ay cytidine. Sa Watson-Crick na baseng pagpapares, ito ay bumubuo ng tatlong mga bigkis hydroheno kasama ang guanine.
