Й, й (Short I) is a letter in the Cyrillic alphabet. It is made of the Cyrillic letter И (which resembles reversed Latin capital N), with a breve.

It is the 11th letter in the Russian alphabet, and in Russian is called И краткое (I kratkoye or "short I").

It is the 14th letter in the Ukrainian alphabet, and in Ukrainian is called Йот, (Yot) or Ий (Yi, pronounced [ɪj]).

In both languages this is a semivowel pronounced [j] (as in English yellow), which can be used to form diphthongs like ai in aisle, ei in vein, oi in oil, and ui. It is transliterated as j, y, or i using different romanization systems. See Transliteration of Russian into English and Romanization of Ukrainian.

In Serbian and Macedonian, letter Ј is used to represent the same sound.
