  Among various scenarios to explain the acceleration of the universe
expansion, the holographic dark energy (HDE) model has got a lot of enthusiasm
recently. In the derivation of holographic energy density, the area relation of
the black hole entropy plays a crucial role. Indeed, the power-law corrections
to entropy appear in dealing with the entanglement of quantum fields in and out
the horizon. Inspired by the power-law corrected entropy, we propose the
so-called "power-law entropy-corrected holographic dark energy" (PLECHDE) in
this Letter. We investigate the cosmological implications of this model and
calculate some relevant cosmological parameters and their evolution. We also
briefly study the so-called "power-law entropy-corrected agegraphic dark
energy" (PLECADE).
