Hannu Toivonen (born May 18, 1984) is a Finnish professional ice hockey goaltender currently playing for Ilves Tampere of the Finnish SM-liiga.
Toivonen started his pro career with HPK in the Finnish SM-liiga. He was drafted by the Boston Bruins of the National Hockey League (NHL) in the 2002 NHL Entry Draft, and moved to the Providence Bruins of the American Hockey League (AHL) in 2003.
With Andrew Raycroft sitting out due to a contract dispute, Toivonen started the 2005–06 NHL season as the Bruins' backup goaltender. He made his NHL debut on October 8, 2005 against the Pittsburgh Penguins, coming away with an overtime win. He holds the distinction of allowing the first goal of Sidney Crosby's career in that game. On December 1, 2005, he recorded his first NHL shutout, blanking the Ottawa Senators. Toivonen was 9–5–4 with a 2.63 GAA and a .914 SV% before suffering a high ankle sprain in January that effectively ended his season.
