We present the result of the analytical computation of the five-loop term in the beta function which governs the running of $\alpha_s$ --- the quark-gluon coupling constant
in QCD. Using the result, a low-energy theorem and the four-loop QCD decoupling formula, we derive the effective Higgs-gluon-gluon coupling constant in five-loop approximation.
