We present the neutral hydrogen (HI) gas properties of AGN host galaxies selected from the Swift/BAT hard X-ray (14-195 keV) all-sky spectroscopic survey (BASS). Our BASS-HI sample consists of 81 nearby (z < 0.0275) galaxies that are HI-detected in the previous single-dish observations. In this study, we probe the HI morphology and kinematics of 15 galaxies with a relatively high HI flux in order to study how the atomic gas reservoir and/or local environment of a host galaxy potentially affects the AGN activity. For a more comprehensive understanding, we also use the multi-wavelength data including the radio continuum.
