Daniel "Dany" James Heatley (born January 21, 1981, in Freiburg im Breisgau, West Germany) is a Canadian/German professional ice hockey winger currently playing for the San Jose Sharks of the National Hockey League (NHL). Originally drafted by the Atlanta Thrashers second overall in the 2000 NHL Entry Draft, he won the Calder Memorial Trophy as the top NHL rookie in 2002. However, after being responsible for a car accident in the fall of 2003 that killed teammate and close friend Dan Snyder, he requested a trade and was subsequently dealt to the Ottawa Senators.

One of the Senators' perennial leading scorers during his tenure with Ottawa, Heatley set franchise records for single-season goals (50) and points (105). He typically played left wing with linemates Jason Spezza and Daniel Alfredsson. Alternately nicknamed the "CASH Line" (referring to Captain Alfredsson, Spezza, and Heatley), or "Pizza Line" (referring to a Pizza Pizza 'free slice' promotion on nights in which the Senators scored six or more goals at home) the line was consistently among the highest scoring in the NHL since its formation in 2005.

Internationally, Heatley has represented Team Canada in six World Championships, one Olympics and one World Cup of Hockey, as well as two World Junior Championships. In 2008, he surpassed Marcel Dionne as Canada's all-time leader in goals and Steve Yzerman as the all-time leader in points for the World Championships.
