Lithium tellurite is an inorganic compound, with the chemical formula Li2TeO3.

It crystallises in the monoclinic crystal system, with space group C2/c.

[1] It can be prepared by reacting lithium oxide,[2] lithium hydroxide[3] or lithium carbonate[4] with tellurium dioxide.

It reacts with lithium fluoride at high temperatures in a 3:1 stoichiometric ratio to obtain Li7(TeO3)3F.
