The Lake Michigan Conference (LMC) was a college athletic conference affiliated with the National Collegiate Athletic Association (NCAA) at the Division III level for the last 7-8 years of its existence after member schools transitioned up from NAIA. Member institutions were all located in Wisconsin except Dominican University in Illinois. LMC schools joined with some schools from the Northern Illinois-Iowa Conference (NIIC) in the 2006–07 school year, creating the Northern Athletics Conference (NAC, now known as the Northern Athletics Collegiate Conference, or NACC).
