Waterdown District High School is located at 215 Parkside Drive, Waterdown, Ontario, and is a member of the Hamilton-Wentworth District School Board.
A high school was first established in the Waterdown District in 1853.
Prior to the 2012 school year, the school saw a $23.9-million expansion of its facilities to accommodate new home construction.
In 2017, Waterdown teacher Rob Flosman won a Governor General's Award for creating a history museum inside of the school. The student-run museum opened in 2013 and contained over 700 artifacts.
