We have succeeded in growing a single crystal of CeNiIn4 with the orthorhombic crystal structure by the In-flux method. CeNiIn4 is found to order antiferromagnetically below 1.4 K, with a successive change of the magnetic structure below 0.75 K. The magnetic phase diagram was formed by the specific heat and magnetization measurements. The electronic specific heat coefficient is determined as 80 mJ/K2·mol. From these experimental results it is concluded that CeNiIn4 is a usual 4f-localized compound.
