Jani Lax (born October 26, 1977) is a Swedish professional mixed martial artist and occasional kickboxer, who competes in the Lightweight division.
He has fought around the world in a number of promotions including Finnfight, K-1, M-1 Global and Shooto.
Lax began his mixed martial arts career in 1999 with Finnfight, one of the largest promotions in the Nordic countries and known for its brutal no-holds-barred rules.
He lost his debut against Marcus Peltonen by knockout in the first round, but went on to defeat Joachim Hansen in his next bout.
In May 2010, he returned to the ring for the first time in almost three years and submitted Danny van Bergen at an M-1 Global event in Helsinki.
