Alexander Mackenzie High School, formerly known as Don Head Secondary School is a public secondary school with classes for students in grades 9 through 12, located in Richmond Hill, Ontario, Canada. The school opened in 1969 as Don Head Secondary School and was renamed Alexander Mackenzie High School in 1992, in honour of Major Addison Alexander Mackenzie, a Richmond Hill resident and philanthropist.

It was announced in October 2008 that AMHS will join Huron Heights S.S., Unionville High School, and Westmount Collegiate as one of the four high schools in York Region to offer a specialized arts program. This program is known as ARTS Mackenzie and encompasses dance, theatre arts, music and visual arts.

In 2017, AMHS, along with G.W. Williams SS, Maple HS, Miliken Mills HS, joined Bayview SS as the board's IB Diploma Programme schools.

Facilities
The original school building was built in 1969 and in 1992 a new wing was added in order to accommodate both the increase in student population and the change in school program. A second addition of 10 classrooms opened in the spring of 2002. The school has two gyms, one larger than the other. The school also has three music rooms, one for vocals, one for strings, and another for band.

Character Matters
In 2003, the Town of Richmond Hill contributed 10 "Character Matters" signs to the school as part of an initiative that encourages young adults to become more involved in their community. This event featured guest speaker Wendel Clark, the former Toronto Maple Leafs Captain.

Guest speakers, such as local Toronto playwrights and actors as well as guests from the Stratford Festival, are brought in for workshops, such as film acting and stage combat. Students are also given opportunities to expand their portfolios through class assignments, local festivals such as The Ontario Drama Festival, and exposure to new forms of stage and film.

Alexander Mackenzie High School offers math in all grades. It also offers opportunities for students to write different math contests, such as Waterloo Math Contest and American Math Competition.

Music
ARTS Mackenzie's music department offers courses in instrumental band, strings, vocal music, classical guitar, piano, and musical theatre. Approximately 30% of the students at Alexander Mackenzie are involved in the music program. The senior or "Symphonic Band" is well decorated and consistently attains gold or platinum in competitions. However, the music program also leads many other ensembles for both singers and students playing instruments, such as concert band, intermediate band, jazz band, man choir, women's choir, chamber choir, concert choir (Mackenzie singers), jazz choir, and more. There is also a musical theatre course that is open to all students in grades 10–12. Every year, the students in the double-credit course rehearse a musical that they perform at the Richmond Hill Centre for the Performing Arts in December. The musical selections rotate between classical (e.g. The Wizard of Oz), contemporary (e.g. Beauty and the Beast), and popular (e.g. Les Misérables).
