Relativistic {ital O}({alpha}{sup 2}) corrections to the orthopositronium decay rate are calculated on the basis of a local quasipotential equation. We take into account the necessary contributions resulting from the amplitude of three-photon decay, the normalization condition of the wave function, and the second-order perturbation theory.
