We propose an holographic k-essence and dilaton models of dark energy. The correspondence between the k-essence and dilaton energy densities with the holographic density, allows the reconstruction of the potential and the fields for the k-essence and dilaton models in flat FRW background. For the proposed infrared cut-off the reconstruction was made for the two cases of the constant α: for α<1 the model presents phantom crossing and the reconstruction was made in the region before the ω=-1 crossing for the EoS parameter. The cosmological dynamics for α>1 was also reconstructed. The reconstruction is consistent with the observational data.
