Marek Svatoš (born June 17, 1982) is a Slovak professional ice hockey forward who currently plays for the Ottawa Senators in the National Hockey League (NHL). In the 2010–11 season, Svatoš had played for Avangard Omsk of the Kontinental Hockey League (KHL) before signing with the St. Louis Blues of the NHL. He was claimed by the Nashville Predators, before being later waived and claimed by Ottawa.
Svatoš was drafted 227th overall by the Colorado Avalanche in the 2001 NHL Entry Draft. He played his first NHL games for the Avalanche in the 2003–04 season. Following a strong performance in the Avalanche's second round loss in the playoffs, he returned to the Avalanche's AHL affiliate, the Hershey Bears, during the 2004 NHL Lockout. Svatoš recorded his first career hat-trick in the NHL against the Calgary Flames in a 7–3 win on October 10. He was chosen to play in the 2006 Olympic Games in Turin, Italy as part of the Slovakian national team.
On March 9, 2006, it was announced that Svatoš sustained a fracture on his right shoulder that forced him to miss the rest of the 2005–06 season. At the time of his injury, Svatoš led the NHL in game-winning goals with nine, which tied an NHL record for game-winning goals by a rookie. He was also one of the top rookie scorers with 32 goals.
