Strathcona Girls Grammar School is an independent, Baptist, day school for girls, located in Canterbury, an inner-eastern suburb of Melbourne, Victoria, Australia.

Established in 1924 by Florence Livingstone and Henrietta Hughes, the school currently caters for approximately 800 students from Preparatory to Year 12 over three campuses. Year nine girls attend Tay Creggan, an historic building on the Yarra River in Hawthorn. Years 7 to 8 and 10 to 12 are located in Canterbury, and the primary school is located in a newly renovated purpose-built premises in close proximity to the Main Campus in Canterbury.

The school is affiliated with the Junior School Heads Association of Australia (JSHAA), the Association of Heads of Independent Schools of Australia (AHISA), the Association of Independent Schools of Victoria (AISV), the Alliance of Girls' Schools Australasia (AGSA), and is a founding member of Girls Sport Victoria (GSV).

Strathcona was established in 1924 by its founding principals, Florence Livingstone and Henrietta Hughes, with a small number of pupils, both boys and girls.

In 1942 the school was purchased by the Baptist Union for the purpose of establishing a Baptist school for girls, and the school was renamed Strathcona Baptist Girls Grammar School.

Ms Featherstone commenced as headmistress in 1943, serving the school for 10 years. Enrolments increased rapidly and despite strict building restrictions after the Second World War, facilities were expanded providing for up to 200 girls.

In November 1969 Strathcona purchased the historical building 'Tay Creggan' and it is now the Year 9 campus, located in Hawthorn on the banks of the Yarra River. Built in 1893 in the Queen Anne style as a family home, it became an important and fashionable part of Hawthorn social life. It was designed by architect Guyon Purchas for his own use. He was later forced to declare bankruptcy and sell the house.

There have been a total of nine principals (formerly headmistresses) of Strathcona since the school was established in 1924. Note, between 1924 and 1941 there were two headmistresses at the same time who were the co-founders of the school.
