Telluric acid is a chemical compound. It is an acid. Its chemical formula is H₆TeO₆. It contains hydrogen and tellurate ions. It contains the TeO₆^6- form of the tellurate ion.

Telluric acid is a weak acid. It reacts with strong bases to make tellurates. It is a powerful oxidizing agents. It can be dehydrated to make tellurium trioxide. The metatelluric acid, H₂TeO₄, does not exist.

Telluric acid can be made by reacting tellurium dioxide with chromium trioxide or hydrogen peroxide.

It is used to make other tellurates such as sodium tellurate.
