Woodhaven (population 12,875) is a city in southern Downriver. The boundaries are formed by King Road to the north, to a point one-half mile east of Allen Road (north of Van Horn), then Reeck Road (south of Van Horn), all to the east, Vreeland Road to the south, and to a point between Hall Road and Telegraph Road to the west. Major thoroughfares include Allen Road, West Road, and Van Horn Road. Interstate 75 also runs through the city. The current mayor is Patricia Odette.

Woodhaven, named for a New York City borough village of the same name, officially became a city in 1965 from an area of Brownstown Township, and is additionally one of the few cities remaining Downriver with two different ZIP codes (48183, 48134). Additionally, Woodhaven is one of the few cities served by two school districts: the southern part of the city is served by neighboring Gibraltar's school district.

Ford Motor Company's Woodhaven Stamping Plant has been the main city industry since its official opening in 1966. Prior to that, the township land's biggest contributor was White Star Refinery, which had its beginnings in the 1920s. Later renamed Socony-Vacumn in the 1940s and then Socony-Mobil refinery by the 1960s, the facility was deactivated in the 1980s and was cleared later that decade to form part of the current day's central business district for the city. The closure of Socony would mean the Marathon Oil Refinery in Melvindale would become Downriver's only remaining refinery.

Perhaps the most famous site in the city limits today is the Detroiter Truck Stop, heralded as one of Michigan's largest when it opened across from the Woodhaven Stamping Plant site in 1964.

Woodhaven was also the city housing the WonderDome, an inflatable structure that was located across I-75 from the Detroiter Truck Stop. The first of its kind in Metro Detroit, it was designed as an indoor golf driving range, but could also hold softball tournaments and other civic happenings. Opened after numerous construction delays in November 1988, the WonderDome would fall victim to a windstorm on January 20, 1990. Despite assurances from the project's contractor that the dome could withstand winds in excess of 100 MPH, top windstorm winds were in the 65-70 MPH range when the dome deflated. Its status was left in limbo for the better part of two years before the remainder of the damaged structure was removed by 1993.
