The 2009 NHL Entry Draft was the 47th Entry Draft. It was held on June 26–27, 2009, at the Bell Centre in Montreal, Quebec. The Draft was part of the Montreal Canadiens' centennial celebrations. National Hockey League teams took turns selecting amateur ice hockey players from junior, collegiate, or European leagues. The New York Islanders, who finished last overall in the 2008–09 NHL season, retained the first overall selection following that year's NHL Draft lottery.
