We study the quasinormal modes of scalar field perturbations in the\nbackground of non-Abelian hyperscaling violating Lifshitz black holes. We find\nthat the quasinormal frequencies have no real part so there is no oscillatory\nbehavior in the perturbations, only exponential decay, that is, the system is\nalways overdamped, which guarantees the mode stability of non-Abelian\nhyperscaling violating Lifshitz black holes. We determine analytically the\nquasinormal modes for massless scalar fields for a dynamical exponent z=2 and\nhyperscaling violating exponent \\θ>-2. Also, we obtain\nnumerically the quasinormal frequencies for different values of the dynamical\nexponent and the hyperscaling violating exponent by using the improved\nasymptotic iteration method.\n
