Launceston Church Grammar School

Launceston Church Grammar School (informally Launceston Grammar or simply Grammar, commonly abbreviated to LCGS) is an Anglican co-educational private school in Launceston, Tasmania, Australia for Early Learning through to Grade 12.

Although founded in 1846, the present school was formed in 1982 from the amalgamation of the boys' Launceston Grammar School and girls' Broadland House Church of England Girls' Grammar School. The school celebrated its 175th birthday on the 15th of June 2021 and retains its longevity, being the longest continuously running independent school in Australia and Tasmania, and being the oldest form of private secondary education in Tasmania. The school is also the second-oldest form of education in Tasmania, after Christ College, Tasmania, the oldest form of education in Australia, now used as a residential college of the University of Tasmania.

Launceston Grammar is affiliated with Association of Heads of Independent Schools of Australia (AHISA), the Independent Primary School Heads of Australia (IPSHA), the Australian Boarding Schools' Association (ABSA), and the Sports Association of Tasmanian Independent Schools (SATIS).

The school competes mainly with Scotch Oakburn College and St Patrick's College, Launceston for student numbers, the three being the only large-scale private schools in Launceston.
