A krai or kray (/kraɪ/; Russian: край, plural: края́, kraya) is one of the types of federal subjects of modern Russia, and was a type of geographical administrative division in the Russian Empire and the Russian SFSR.
Etymologically, the word is related to the verb "кроить" (kroit'), "to cut". Historically, krais were vast territories located along the periphery of the Russian state, since the word krai also means border or edge, i.e., a place of the cut-off. In English the term is often translated as "territory". As of 2015[update], the administrative usage of the term is mostly traditional, as some oblasts also fit this description and there is no difference in constitutional legal status in Russia between the krais and the oblasts.
