Southfield is a city in Oakland County in the U.S. state of Michigan. An inner-ring suburb of Detroit, Southfield lies roughly 15 miles (24.1 km) northwest of downtown Detroit. The city had a population of 76,618 at the 2020 census.

Southfield home to multiple business districts, including the Southfield City Centre (an edge city which contains the tallest building in Detroit's suburbs) and the area surrounding the former Northland Center shopping mall. It is also home to Lawrence Technological University. The city was originally part of Southfield Township before incorporating in 1958. The autonomous city of Lathrup Village is an enclave within Southfield.

Southfield is also a historic center of Mid-century modern architecture in Michigan, with many examples being found across the city.

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.

The Southfield Fire Department was formed on April 6, 1942, and the Southfield Police Department in 1953. In the 1950s, cities and villages began to incorporate within the township, including Lathrup Village in 1950, and Beverly Hills in 1957. Most of what was left of the township was formally incorporated as a city on April 28, 1958, to protect it from annexation attempts by the municipalities within it and especially by adjacent Detroit; whites who had migrated to the suburbs did not want to be associated with Detroit's expanding black community.

City Hall was built in 1964 as part of the new Civic Center complex, which also became home to Southfield's police headquarters. The Civic Center was expanded in 1971 to include a sports arena with swimming pool. Evergreen Hills Golf Course was added in 1972, and in 1978, a new public safety building, the Southfield Pavilion, and a new court building were added. In 2003, an expanded and redesigned Southfield Public Library opened to the public on the Civic Center grounds, featuring state-of-the-art facilities. Outside the Civic Center complex, Southfield has municipal parks and recreation facilities, largely developed in the 1970s, including Beech Woods Recreation Center and John Grace Community Center.

Duns Scotus College is now the home of Word of Faith Christian Center. In 2016, the site was the center of local controversy over a proposed oil drilling site. Due to sustained opposition and environmental concerns, the plan was cancelled.
