Courtice (pronounced "Curtis") is a community located in Ontario, Canada about 60 km east of Toronto, adjacent to Oshawa and west of Bowmanville in the Municipality of Clarington. Courtice Road (Durham Road 34) connects with Highway 401 at Interchange 425, providing arterial access to the community. Darlington Provincial Park is located just south of Courtice.

The area was first settled in the late 18th century, and Courtice takes its name from one of the early families in the area. A post office with the name was established in the mid 19th century, and rail connections became available on both the Canadian Pacific and Grand Trunk main lines which passed south of the village closer to Lake Ontario. Courtice remained primarily a small rural village well into the 20th century, but housing developments beginning in the mid-1980s quickly caused the population to grow from about 1,500 to over 20,000. By the mid-1990s growth had slowed somewhat, although new housing developments are continuing and the area remains popular due to relatively low prices. Housing is primarily single-family detached residential, and most residents travel to Toronto or points west in Durham Region for employment. Commercial development is centred along Highway 2, with particular concentrations at the intersections with Townline Road (at the boundary with Oshawa) and Courtice Road.
