Tommi Satosaari (born February 17, 1975, in Jyväskylä, Finland) is a Finnish professional ice hockey goaltender.
Satosaari played his first five years as a pro with his hometown team JYP in the SM-liiga. When the team unloaded several players after a disappointing 1999-2000 season, Satosaari made his way abroad, spending the next season with the Newcastle Jesters in the British Ice Hockey Superleague (BISL). Satosaari then returned to Finland for a season with Ässät, and in 2002-2003 he represented REV Bremerhaven in the German second league in the fall, and finished the year with Ilves. In 2003-2004 Satosaari returned to Newcastle to play for the Newcastle Vipers in the British National League before and moving to HK Olimpija Ljubljana in Slovenia for the 2004-2005 season.
Returning to JYP, Satosaari was made Sinuhe Wallinheimo's backup, but when Wallinheimo performed exceptionally well Satosaari transferred to Pelicans for the rest of the season.
