Stannane /ˈstæneɪn/ or tin hydride is an inorganic compound with the chemical formula SnH₄. It is a colourless gas that ignites on contact with air. SnH₄ is a heavy analogue of methane but much less robust. In contrast to this rarely used species, stannane also refers to a large collection of organotin compounds.

Stannane can be prepared by the reaction of SnCl₄ and lithium aluminium hydride according to the following idealized equation:¹

SnCl₄ + Li[AlH₄] → SnH₄ + LiCl + AlCl₃

Stannane decomposes slowly at room temperature to give metallic tin and hydrogen.¹

SnH₄ → Sn + 2H₂

Organotin hydrides are more stable, e.g. triphenyltin hydride, also known as triphenylstannane.

The volatility of stannane is potentially relevant to production of microchips.²
