Axion-like Particles (ALPs) and Hidden Photons (HPs) are candidates of cold dark matter. These bosons are experimentally interesting because they are absorbed by materials through an interaction analogous to a photoelectric effect, transferring the energy equivalent to their rest mass to recoil electrons. XMASS is an experiment aiming at direct detection of dark matter, using single-phase liquid-xenon scintillator at the Kamioka Observatory in Japan. With its low background environment, the XMASS detector has a good sensitivity to the electron recoil signals from ALPs and HPs. Analyzing 800 live-days of XMASS data with 327 kg liquid xenon in the fiducial volume, we set the most stringent upper limits on the coupling constant g Ae of ALPs and the parameter for kinetic mixing α′/α of HPs in the mass range from 40 to 120 keV/c 2 .
