氯酸锂是一种无机化合物，属于氯酸盐，为一种盐类，其化学式为LiClO₃。氯酸锂是一种氧化剂，在高温下则是强氧化剂。

由碳酸锂和氯酸反应制得.

Li₂CO₃ + HClO₃ → 2LiClO₃ + CO₂↑

此外，也可从硫酸锂和氯酸钡进行化学合成

Li₂SO₄ + Ba(ClO₃)₂ → LiClO₃ + BaSO₄↓

Lithium chlorate is the inorganic chemical compound with the formula LiClO₃. Like all chlorates, it is an oxidizer and may become unstable and possibly explosive if mixed with organic materials, reactive metal powders, or sulfur.

It can be manufactured by the reaction of hot, concentrated lithium hydroxide with chlorine:
