The NHL Entry Draft (French: "Repêchage d'entrée dans la LNH" ) is an annual meeting in which every franchise of the National Hockey League (NHL) systematically select the rights to available ice hockey players who meet draft eligibility requirements (North American players 18–20 years old and European/international players 18–21 years old; all others enter league as unrestricted free agents).
 The NHL Entry Draft is held once every year, generally within two to three months after the conclusion of the previous season.
 During the draft, teams take turns selecting amateur players from junior or collegiate leagues and professional players from European leagues.

The 2008 NHL Entry Draft was the 46th NHL Entry Draft.
 It was hosted by the Ottawa Senators at Scotiabank Place in the city of Ottawa, Ontario, Canada, on June 20–21, 2008.

 The actual 2005 drafting was held in Ottawa's Westin Hotel instead of the Corel Centre, as Canadian Tire Centre was then known.
 As a result of 2005's abridged draft, Ottawa was compensated with the 2008 draft.
