Southfield is a city in Oakland County in the U.S. state of Michigan. As of the 2010 census, the city had a population of 76,618. As a northern suburb of Detroit, Southfield shares part of its southern border with Detroit. The city was originally part of Southfield Township before incorporating in 1958. The autonomous city of Lathrup Village is an enclave within Southfield. The city is home to the Southfield Town Center complex, which includes five connected office buildings. The tallest of these, 3000 Town Center, is 402 feet (122.5 m) tall; it is the state's second-tallest building outside Detroit (after the River House Condominiums in Grand Rapids) and the state's 16th-tallest building overall.

Southfield was surveyed in 1817 according to the plan by Michigan territorial governor Lewis Cass. The first settlers came from nearby Birmingham and Royal Oak, Michigan, as well as New York and Vermont. The area that became Southfield was settled by John Daniels in 1823. Among the founders were the Heth, Stephens, Harmon, McClelland and Thompson families.

Town 1 north, 10 east was first organized as Ossewa Township on July 12, 1830, but the name was changed to Southfield Township 17 days later. The township took its name from its location in the "south fields" of Bloomfield Township. A US post office was established in 1833 and the first town hall built in 1873.
