Emmet County is a county in the U.S. state of Michigan. As of the 2000 census, the population was 31,437. The county seat is Petoskey. The county was formed April 1, 1840, from Mackinac County. It was first named Tonedagana County and renamed Emmet County on March 8, 1843. Emmet County remained attached to Mackinac County for administrative purposes until county government was organized in 1853. The county was named for the Irish patriot Robert Emmet, who was hanged as a traitor to the British government at the age of 23. Sixteen counties were renamed in 1843 and five were given names of Irish origin, supposedly in deference to the increasing presence of settlers in Michigan with an Irish background.
