Marlette is known as "The Heart of the Thumb" due to its location in Michigan. It is a small community with a golf course, public pool, and a municipal airport. Crops grown here include corn, beans and sugar beets. Marlette is a closely knit rural community, but an hour drive will take you to several urban centers such as Saginaw, Bay City, Flint and Port Huron. It is considered a part of the Flint/Tri-Cities region.
Marlette was first settled in the mid-19th century by people from Ontario who sought tall timber and fertile soil. The city got its name from the family of settlers, "Marlatt" who carved their name on a log shanty.
