Magnetic characteristics have been studied for a TbPd2Si2 single crystal from measurements of magnetic susceptibility, high field magnetization, and specific heat. The antiferromagnetic ordering below T_{\text{N}}=15 K has been confirmed. The easy magnetization direction is the [110] direction in the basal plane at high magnetic fields. The [110] magnetization is saturated above 24 T and reaches M_{\text{s}}=9.0 \mu_{\text{B}}. Multistep metamagnetic behaviors appear in the basal plane magnetization processes. A one-step metamagnetic transition appears in the [001] magnetization process and persists up to 28 K above T_{\text{N}}. Strong magnetic anisotropy is observed between the [110] and [100] directions for high fields, and between the [001] and directions in the basal plane. Magnetic phase diagrams are constructed, in which there are four magnetic ordered phases. The main features of anisotropic magnetic behaviors are almost explained by crystalline electric field effects.
