The two subspecies are:
C. c. carpio is native to much of Europe (notably the Danube and Volga Rivers).

C. c. yilmaz (Deniz carp) is from Anatolian Turkey (notably around Çorum).

A third subspecies, C. c. haematopterus (Amur carp) native to eastern Asia, was recognized in the past, but recent authorities treat it as a separate species under the name C. rubrofuscus.
The common carp and various Asian relatives in the pure forms can be separated by meristics and also differ in genetics, but they are able to interbreed.
Common carp can also interbreed with the goldfish (Carassius auratus); the result is called Kollar carp.
