1,2-Dithiolane is an organosulfur compound with the formula S₂(CH₂)₃. It is also classified as a heterocycle derived from cyclopentane by replacing two methylene bridges (−CH₂− units) with a disulfide group. 1,3-Dithiolane is an isomer. The parent molecule is unimportant but substituted derivatives, especially lipoic acid and its derivatives, are often essential for life. Several occur naturally.

The parent 1,2-dithiolane is the disulfide derived from 1,3-propanedithiol. It is however unstable with respect to oligomerization. In general, 1,3-dithiols are superior reductants relative to monothiols.
