Petr Sýkora (Czech pronunciation: [ˈpɛtr̩ ˈsiːkora]; born November 19, 1976) is a Czech former professional ice hockey right winger who played in the National Hockey League (NHL) for the New Jersey Devils, Mighty Ducks of Anaheim, New York Rangers, Edmonton Oilers, Pittsburgh Penguins, and Minnesota Wild.

As part of the Devils' effective "A-line," with Patrik Eliáš and Jason Arnott, he helped lead the team to a Stanley Cup in 2000 against the Dallas Stars.

While the 2004–05 NHL lockout was in effect, Sýkora played for Metallurg Magnitogorsk of the Russian Superleague (RSL), scoring 31 points in 45 games.

[6] After completing the season with New York, it was announced on July 7, 2006, that Sýkora would not return to the Rangers, and he was subsequently signed to a one-year deal with the Edmonton Oilers.

Bolstering their lineup at the trade deadline, the Penguins acquired wingers Bill Guerin and Chris Kunitz, resulting in decreased ice time for Sýkora.

He played in seven of the Penguins' 24 post-season games as the team returned to the Stanley Cup Finals against the Red Wings for the second straight year.

Sidelined for the deciding Game 7, he forced his swelled foot into a skate to join the Penguins on the ice for their post-game celebration after defeating the Red Wings 2–1.

[13] On January 28, the Wild announced that Sýkora had cleared unconditional waivers, officially making him an unrestricted free agent.

After recording 13 points (five goals and seven assists) over 13 games while playing on a line with Martin Straka and Jan Kovář, he signed a tryout contract with Dinamo Minsk of the Kontinental Hockey League (KHL) on November 11, 2010.

On September 12, 2011, it was announced that Sýkora would attend the New Jersey Devils' training camp on a tryout, hoping to return to the team that drafted him into the NHL.
