Hamilton Grammar School is a secondary school serving the town of Hamilton and other areas of South Lanarkshire.
Situated in central Hamilton, Scotland, its predecessors can trace their history back to the year 1452. With the introduction of comprehensive schools and the abolition of selective schools such as Hamilton Academy in the early 1970s, Hamilton Grammar School was formed as a new school, using the buildings of the former Hamilton Academy and the nearby St. John's Grammar School, Hamilton.
Famous former pupils of Hamilton Grammar or its predecessor schools include the economist (Sir) Alexander Cairncross, the politician Margo MacDonald, the novelist Robin Jenkins, author and motoring writer James Currie, the product designer Philip Ross (SafeHinge), pioneer photographer James Craig Annan, doctor and chemist William Cullen and Ali Richardson, the drummer of the rising Death Metal band Bleed From Within.
Hamilton Academy gave its name to Hamilton Academical F.C., the football club, which was founded in 1874 by the Rector and pupils.
The current Hamilton Grammar building was built in 1913 as the Hamilton Academy building. The building underwent an £8 million improvement in 1995, when the original building was retained and fully renovated, with an additional building extension attached to rear. The new building contains science and technical facilities. In 2004, a communicational disorders unit was added to the school.
A new Physical Education centre was built at the rear of the school. Building work started in June 2008 and was completed August 2009 . This replaced the old Physical Education department which was at the back of St John's Primary School.
