We show renormalization group invariants in neutrino sector. These are found from a simple analytical discussion of Majorana mass matrix for light neutrinos. There are four invariants, which are ratios among elements of the mass matrix. They are independent of neutrino mass ordering and a parameterization of mixing matrix for the lepton sector. We also investigate two running parameters of renormalization group equations, which can directly show neutrino mass matrix at the high energy scale.
