Thiazolines (/θaɪˈæzoʊliːnz/; or dihydrothiazoles) are a group of isomeric 5-membered heterocyclic compounds containing both sulfur and nitrogen in the ring. Although unsubstituted thiazolines are rarely encountered themselves, their derivatives are more common and some are bioactive. For example, in a common post-translational modification, cysteine residues are converted into thiazolines.

The name thiazoline originates from the Hantzsch–Widman nomenclature.
