In non-commutative phase space,energy spectrum of three-mode coordinate-momentum coupling harmonic oscillator is analyzed by using the invariant eigen-operator method. The explicit expressions for two kinds of three - mode harmonic oscillators: no coupling and coordinate - momentum coupling are obtained. Some expressions λ0,1 and λ1,1 have be connected with non-commutative parameters θ and φ,others λ0,2 and λ1,2 do not.It is discussed about theeffect of coupling parameters on energy spectrum of three-mode coordinate-momentum coupling harmonic oscillator.The results show that the coupling parameters κ and η have the similar effect on the λ1,1 .Furthermore,they do not have any effect on the λ1,1 when κ and η are equal.
