Tiocijanska kiselna je hemijsko jedinjenje sa formulom HSCN, koje postoji kao smeša sa izomernim jedinjenjem izotiocijanskom kiselinom (HNCS).^[8] Ona je sumporni analog cijanske kiseline (HOCN).

Ona je umereno slaba kiselina, sa pKa od 1,1 na 20 °C i ekstrapolisanom jonskom jačinom od nula.^[9]

Smatra se da HSCN ima trostruku vezu između ugljenika i azota. Ona je primećena spektroskopskim putem ali nije bila izolovana kao čista supstanca.^[10]
