Indianfields Township is a civil township of Tuscola County in the U.S. state of Michigan. The population was 6,048 at the 2010 Census, making it the largest unit of local government in the Thumb of Michigan. However, this figure includes most of the population of the city of Caro, which is administratively autonomous of the township, and thus the 2020 Census will show a substantial decrease in the township's population.
