Thiete is a heterocyclic compound containing an unsaturated four-membered ring with three carbon atoms and one sulfur atom. It is more commonly encountered not on its own, but in anellated derivatives, several of which have been synthesized. Thietes are generally not very stable.

Thiete is a valence isomer of the unknown compound thioacrolein (CH₂=CHCH=S) Thiete has been shown to be planar, with a C-S-C angle of 76.8 degrees.

Benzothietes are thietes annulated to benzo group. Such species are prepared by flash vacuum pyrolysis of 2-mercaptobenzyl alcohols. They are precursors to other S-heterocycles.

Thiete 1,1-dioxides are sulfones, the parent being C₃H₄SO₂. They are more stable than the parent thietes. Substituted thiete-1,1-dioxides can also be prepared by [2+2] cycloaddition of sulfenes and ynamines.
