Lillian Osborne High School is a high school located in the Terwillegar community of Edmonton, Alberta, Canada, and serves the south west area of the city for Edmonton Public Schools. It was named in 2009 in honour of Edmonton's first female school teacher, Lillian Osborne, who was 20-years-old when she started teaching in 1889 in what was then the town of Edmonton, North-West Territories; the school named for her has a larger "population" (2,116 students) than the entire population of Edmonton when she started teaching.^[4][5]
