硼氢化锂是一种无机化合物，化学式为LiBH₄，为强还原剂。

硼氢化锂可以和甲醇反应，生成氢气和硼甲氧化锂。

LiBH₄ + 4MeOH → Li[B(OMe)₄] + 4H₂↑

Lithium borohydride (LiBH₄) is a tetrahydroborate and known in organic synthesis as a reducing agent for esters. Although less common than the related sodium borohydride, the lithium salt offers some advantages, being a stronger reducing agent and highly soluble in ethers, whilst remaining safer to handle than lithium aluminium hydride.
