类韵（英语：Assonance）是西方诗歌里的一种押韵形式，意思是一行韵文或一首诗里头有元音韵的重复。

Assonance is the repetition of vowel sounds to create internal rhyming within phrases or sentences, and together with alliteration and consonance serves as one of the building blocks of verse. Assonance does not have to be a rhyme; the identity of which depends merely on sequence of both vowel and consonant sounds. Thus, assonance is a resemblance of units that are generally less than a syllable.
