High-field magnetization up to 18 T and magnetic susceptibility measurements have been performed on a TbCu2Si2 single crystal. The magnetic susceptibility shows an antiferromagnetic behaviour with two anomalies at Tt 9.1 K and TN 11.9 K. The easy magnetization direction is the  direction in the basal plane. The magnetization along the easy direction shows a multi-step metamagnetic process in low fields. It is almost saturated above 8 T and reaches 8.7 μBat 16 T. A strong magnetic anisotropy between the  and  directions is observed at high fields. A one-step metamagnetic transition appears around 13 T at 4.2 K in the hard  magnetization process. This transition survives at 13 K even above TN. These magnetic behaviours are discussed from an analysis of crystalline electric field.
