King City is an unincorporated Canadian community in King, Ontario located north of Toronto. It is the largest community in King Township, with 1,629 dwellings and a population of 4,902 as of the Canada 2006 Census.

Originally a small settlement styled Springhill, King City has slowly grown since the arrival of the railway in 1853.

King City is characterized by rolling hills and clustered temperate forests in the Eastern Great Lakes lowland forests ecoregion. Numerous kettle lakes and ponds dot the area. Creeks and streams from King City, the surrounding area, and as far west as Bolton and as far east as Stouffville are the origin for the East Humber River.

Situated entirely on the southern slope of the central portion of the Oak Ridges Moraine and its watershed, numerous disputes about planning and development have occurred municipally. In the 2000s, the central issue has been the controversial Big Pipe, a sewerage system connecting to the much larger Durham-York Sewage System (see Politics for further discussion).

Numerous stables and other farms have been established on the 147.938 km² of land area occupied by the township.

The King City Community Centre and King City Arena host numerous activities, such as youth hockey league matches and yoga classes. They also host many community events throughout the year, and some public King Township meetings.

Leagues for girls and boys hockey, tennis, soccer, and baseball exist, and a number of clubs provide other avenues for kids to enjoy and learn.

King City Memorial Park, next to the arena, has two baseball fields, several soccer fields, two children's playgrounds, and four tennis courts (two with lighting). An open, covered area is used for public events and picnics.

A portion of the extensive Oak Ridges Trail passes through King City. The community is creating its own trail network, the King City Trail; the two networks are currently not connected.

Private recreation facilities include St. Edmunds Sparkling Cricket Club cricket facility operated by the Maple Leaf Cricket Club, and two golf clubs: King's Riding Golf Club and King Valley Golf Club.

Residents are within a ten-minute commute to recreation in other communities. The Maple Community Centre, operated by the City of Vaughan, offers services and memberships to non-Vaughan residents. Services available include a fitness centre, a pool for lap and family swimming, and a public library. Aurora and Richmond Hill also have facilities, both private and public, easily accessible to King City residents.
