The Michigan Association of Counties (MAC) is a nonpartisan, nonprofit organization that represents and advocates for all county commissioners in Michigan. Established in 1898, MAC is dedicated to promoting education, communication, and cooperation among county government officials. As the counties' voice at the state and federal level, MAC provides legislative support on key issues that impact counties.

MAC offers a range of services to strengthen and enhance member employee benefit packages. Additionally, MACAO (Michigan Association of County Administrative Officers) provides administrative support for counties. MAC also produces a podcast called Podcast 83, which covers news, stories, and trends related to Michigan's 83 counties.

In addition to their services, MAC hosts events and conferences, including the upcoming 2023 Michigan Counties Annual Conference, which will feature an Anniversary Gala and workshops on important county issues. MAC is excited to celebrate its 125th Anniversary and will be sharing special events, promotions, and historical information throughout the year. For resources, MAC has created a digital resource page to assist county leaders in developing public health strategies funded by county shares of the national opioid settlement.

The page includes an overview of the opioid crisis, links to resources on maximizing public health, and webinar recordings from the Michigan Department of Health and Human Services. For those interested in learning more about counties in Michigan, MAC provides a membership directory and publishes 'Michigan Counties' magazine
