Michael "Mike" Lanigan is an entrepreneur and IndyCar Series team owner.

Lanigan founded a division of his father's company, Mi-Jack Construction Equipment in Indianapolis in 1973. In 1989 he returned to his hometown of Chicago to become president of the company. The company produces rubber-tire gantry cranes. In 1992 Mi-Jack began sponsoring cars competing in CART and the Indianapolis 500.

Lanigan expanded his sponsorship into team ownership in 2001, joining forces with Eric Bachelart to co-own Conquest Racing which competed in the IndyCar Series in 2001 and 2002, then the Champ Car World Series from 2003 to 2006. Lanigan sold his interest in Conquest following the 2007 season to join the ownership group at Newman/Haas Racing, which became Newman/Haas/Lanigan Racing, a much more successful Champ Car team. N/H/L joined the IndyCar Series following the unification between Champ Car and IndyCar prior to the 2008 season. He was also a partial owner of Carl A. Haas Motorsports in NASCAR in 2007. During the 2010 season, he left the ownership group of Newman/Haas.^{[citation needed]} In December 2010, he joined the ownership team of Rahal Letterman Racing which was renamed Rahal Letterman Lanigan Racing. The team has IndyCar operations and races full-time in the American Le Mans Series.
