Jaakko Tommi Kristian Evilä (born 6 April 1980 in Tampere) is a Finnish former long jumper.

He then improved his personal best jump to 8.19 metres in August, and finished sixth at the 2005 World Athletics Final.

In June 2008 he set a Finnish national record of 8.22 metres in Gothenburg.

He competed in the 2010 Finnish Elite Games and came close to winning the jackpot, having won the long jump at four out of five meetings.

This dropped him into fourth place overall and Levern Spencer of St. Lucia topped the rankings to win the prize.
