Bismuthine (IUPAC name: bismuthane) is the chemical compound with the formula Bi H₃. As the heaviest analogue of ammonia (a pnictogen hydride), BiH₃ is unstable, decomposing to bismuth metal well below 0 °C. This compound adopts the expected pyramidal structure with H–Bi–H angles of around 90°.

The term bismuthine may also refer to a member of the family of organobismuth(III) species having the general formula BiR
₃, where R is an organic substituent. For example, Bi(CH₃)₃ is trimethylbismuthine.
