Kwun Tong Government Secondary School (; often abbreviated as KTGSS) is a co-educational and English-as-Medium-of-Instruction government secondary school. Founded in 1982, it is located at 9 Shun Chi Street, Shun Chi Court, Shun Lee, Kowloon, Hong Kong.
The school was established as a grammar school in 1982 by the Government of British Hong Kong.
In January 2023, the school required teachers to vet speeches from guest speakers and check their presentation materials to correct any "inappropriate remarks", saying that "[s]peakers need to submit their speech or presentation slides in advance, and cannot promote political messages or express a political stance."[1]
