The Mackinac County Jail is in St. Ignace, Michigan. The Mackinac County Jail is operated and managed by the Mackinac County Sheriff’s Office.

The facility is a medium detention center that holds adult inmates. The inmates in this facility are either sentenced or awaiting their trial.

The Mackinac County Jail accepts inmates from surrounding municipalities and towns. They also accept inmates from the St. Ignace Police Department, as they do not have their own long-term lock-up facility.

The Mackinac County Jail receives new inmates to the jail daily. While new inmates are coming in, there are also inmates leaving as well. Inmates are released when they post bail, placed under probation, or on their own recognizance.

The inmates who are not released will have their own bed and be allotted three meals a day.

While inmates are serving their time out in the Mackinac County Jail, they can work throughout the jail such as laundry personnel or a kitchen staff member.  In return for their work, they can shave off a few days from their sentence.

All violent and out of control inmates will be separated from the general population inmates to keep the piece inside the facility.
