Y (minuscule: y) is the twenty-fifth and penultimate letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages, and others worldwide. According to some authorities, it is the sixth (or seventh if including W) vowel letter of the English alphabet. Its name in English is wye (pronounced ), plural wyes.

In the English writing system, it mostly represents a vowel and seldom a consonant, and in other orthographies it may represent a vowel or a consonant.
