Lincoln M. Alexander Secondary School is located in the village of Malton in the city of Mississauga, Ontario (part of the Peel District School Board). It is named after the former federal cabinet minister and Lieutenant Governor of Ontario, Lincoln M. Alexander. Founded in 1968 as Westwood Secondary School, it was renamed in 2000 after it merged with Morning Star Secondary School.

After the merger the school was expanded, creating the present day Geography/Historical Studies wing. This was done in an effort to accommodate more students.

The exterior of the school is architecturally almost an exact copy of Erindale Secondary School, while their interiors remain different.

The high school is located on Morning Star Drive near the intersection of Morning Star Drive and Goreway Drive. Its location is central to the small community of Malton. As a result, it is not serviced by school buses except for the disabled. Adjacent to the high school is Malton Community Centre with its facilities such as a library.
