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 2013 NHL Entry Draft was the 51st NHL Entry Draft.
 All seven rounds of the draft took place on June 30, 2013, at the Prudential Center in Newark, New Jersey.
 The top three selections were Nathan MacKinnon, Aleksander Barkov Jr. and Jonathan Drouin.

 It was held on June 26–27, 2009, at the Bell Centre in Montreal, Quebec.

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 Senators were originally awarded the 2005 NHL Entry Draft, but because of the lockout, that draft was scaled back significantly from its usual format of being open to the public and having many draft-eligible players in attendance.
 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.
