Superconductivity was already detected in 18 Heusler alloys, i.e. ternary intermetallics forming a large class of cubic compounds having the composition TX2Z, where T and X are transition and noble metal atom and Z is sp element. In the paper we present the results of resistivity, dc and ac susceptibility measurements of polycrystalline ZrNi2In. Critical temperature of the compound (defined as the onset of magnetic transition) was equal to Tc = 9 K, surprisingly high for this class of compounds (the maximum value of critical temperature was previously obtained for YPd2Sn and was equal to Tc = 4.64 K).
