We consider finite temperature QCD properties in the dense matter in the framework of a holographic QCD approach. We first propose the simple holographic dual geometry to the QCD with the finite density. We describe the the effect of the Hawking-Page transition. We then study an influence of matters on the deconfinement temperature. Then we investigate the density effect on the meson spectrums. We now study alternative model based on the D7 brane embedding in black D3/D-instanton geometry. This corresponds to the Yang-Mills theory with background gluon condensation. We first consider the zero temperature and zero density limit. Then we extend to the finite temperature and finite density case. In this setup, we study the phase transitions among the chiral symmetry broken phase, chiral symmetry unbroken phase and the baryon phase.
