We report on the discovery of bulk superconductivity in Ni0.05ZrTe3 at Tc=3.1 K, obtained through Ni intercalation. Superconductivity coexists with charge density wave (CDW) state with TCDW=41 K. When compared to the parent material ZrTe3, the filamentary superconducting transition is substantially increased whereas TCDW is suppressed. The analysis of superconducting state indicates that Ni0.05ZrTe3 is an intermediately coupled superconductor.
