Abstract: We study the holographic dark energy model in a generalized scalar tensortheory. In a universe filled with cold dark matter and dark energy, the effectof potential of the scalar field is investigated in the equation of stateparameter. We show that for a various types of potentials, the equation ofstate parameter is negative and transition from deceleration to accelerationexpansion of the universe is possible.
