'''Tiocyansyra''', med äldre benämning ''rodanvätesyra'', är en organisk syra. Det är en vätska med stickande sur lukt, som i fritt tillstånd inte har någon speciell användning. Syran existerar som en blandning med den isomera föreningen isotiocyansyra. Det är en svavelanalogi av [[cyanvätesyra]] (HOCN).<br />
<br />
Däremot är flera av dess salter viktiga, av vilka kan nämnas<br />
<br />
· [[ammoniumtiocyanat]], NH<sub>4</sub>SCN,<br />
<br />
· [[kaliumtiocyanat]], KSCN,<br />
<br />
· [[kvicksilvertiocyanat]], Hg(SCN)<sub>2</sub>.<br />
