Lorenzo Lanzi (born October 26, 1981, in Cesena, Italy) is a professional motorcycle racer most known for competing in the Superbike World championship.

In 2004 he moved to the Supersport World Championship riding for Ducati Breil finishing the season in 5th place.

A series of 8 successive top ten finishes earned him a promotion at the EuroSpeedway Lausitz round where he raced for the Xerox sponsored Ducati factory team in place of the injured Régis Laconi.

He rejoined third, but had missed enough of the track to earn a ride-through penalty, dropping him down the field, although he fought back to 8th.

He took victory in Valencia race 1 - he overtook Troy Bayliss for third on the final lap, just before Max Neukirchner and Carlos Checa collided while battling for the lead.
