Kwun Tong Maryknoll College (Chinese: 觀塘瑪利諾書院; KTMC) is a Catholic boys' secondary school in Hong Kong.

In 1962, the Maryknoll Father Society asked the Education Department for assistance in building a subsidised Anglo-Chinese secondary school in Kwun Tong.

[citation needed] The planning of the school was delayed by the unrest of the late 1960s and the serious inflation which upset all cost estimates.

Due to good reputation and alumni's achievements, there is keen competition among applicants during the admission selection procedure.

In 2002, the first ever student to achieve 10 distinctions (10 As) in the Hong Kong Certificate of Education Examination (HKCEE), Li Ki-kwong, was produced.

Li was then admitted by the Faculty of Medicine of the University of Hong Kong through the Early Admission Scheme and graduated in 2007.

Social services undertaken include collecting second-hand clothes, flag-selling activities for charitable purposes and visiting nursing homes.

In sports, Kwun Tong Maryknoll College has conquered champions in bowling, basketball, cross country, football, trampoline, softball, and swimming competitions.

Besides, KTMC students also participate in other competitions, such as art, business, computer programming, drama, International Physics Olympiad, mathematics, singing, and the Hong Kong Schools Music and Speech Festival.
