We introduce an SU(2)_X^ dark sector without any fermions and then realize a non-abelian kinetic mixing between the dark SU(2)_X^ gauge fields and the standard model SU(2)_L^× U(1)_Y^ gauge fields. While one of the dark gauge bosons becomes a dark photon, the others can keep stable to form a dark matter particle. The nearly degenerate masses of dark photon and dark matter could be tested if the dark photon and the dark matter are both observed in the future.
