Krzysztof Artur Oliwa (pronounced [ˈkʂɨʂtɔf ˈartur ɔˈliva]; born April 12, 1973) is a Polish former professional ice hockey player.

To date, he is the only player from Poland with his name inscribed on the Stanley Cup, as a member of the New Jersey Devils' 2000 championship team.

Nicknamed "the Polish Hammer",[1] Oliwa was a big (6' 5"), intimidating, physical player who played the role of an enforcer.

During his teenage years in Poland, Oliwa worked full-time in a coal mine, followed by a daily hockey practice.

[4] However, Oliwa played enough regular season games to qualify to have his name inscribed on the Stanley Cup, making him the first player born and trained in Poland to have this honor.

After the lockout, in the 2005–06 season, Oliwa was waived by the Devils to make room for Patrik Elias under the new salary cap.

After clearing waivers, the Devils chose not to demote Oliwa to their minor league team in Albany and instead sent him home.
