Troy is a city in Oakland County in the U.S. state of Michigan. A northern suburb of Detroit, Troy is located about 22 miles (35 km) north of downtown Detroit. As of the 2020 census, the city had a population of 87,294, making Troy the largest community in Oakland County, and the 13th-most-populous municipality in the state.

Troy was organized as a township in 1827, and sections of the township incorporated much later into the cities of Birmingham, Clawson, and Royal Oak. The remainder of the township incorporated as the present-day city of Troy in 1955.

Troy has office centers and the Somerset Collection mall.

The earliest recorded purchases of land in what was known as Troy Township occurred in 1819. A couple of years later a settlement known as Troy Corners was established due to Johnson Niles buying 160 acres in the region. The area is currently the north-central area of Troy. In 1827 Troy Township was established. In 1955, Troy was officially incorporated primarily as a strategy for preventing border cities from taking more land. This also helped to establish more robust city services for Troy residents, whose numbers increased rapidly during this time due to Detroiters fleeing the City for the surrounding suburbs.

It was named after Troy, New York, and the ancient city of Troy, as many of the early settlers, as in much of Michigan, originated from New York.
