King George V School, International secondary school in Kowloon City District, Hong Kong.

King George V School is an international secondary institution in Kowloon City District, Hong Kong, serving over 1900 students. The campus comprises several buildings with science laboratories, performing arts spaces, and sports facilities spread across the grounds.

The school traces back to Kowloon College, founded in 1894 on Nathan Road with a building donated by Sir Robert Ho Tung. It was renamed Central British School in 1902 and moved to Ho Man Tin, where the Peel Block, named after Governor Sir William Peel, was completed in 1937. In 1940 it closed and became a British military hospital, then a Japanese hospital during the occupation; it reopened in 1946 with 79 students and took the name King George V School in 1948.

The school motto and school song share the Latin title Honestas Ante Honores, meaning honesty before honours. At the start of the academic year the whole school sings the school song at the awards ceremony. The house system uses four colours for intra-school events and competitions.

The campus covers 41,278 square metres at 2 Tin Kwong Road, Ho Man Tin, with nine teaching blocks, a 25-metre swimming pool, a grass sports field and two drama rehearsal rooms. Peel Block, the two-storey administrative centre, holds the hall, gymnasium, archive room and PTSA shop. The Performing Arts Block and Science Block each have a rooftop garden, the latter with a small open-air theatre.

A truncated Spitfire fuselage was kept in a KGV classroom until the 1950s, stored in the pavilion basement. An Air Commodore had it removed and restored, and it was later placed at the Cenotaph in Central for Remembrance Day. The school motto, Honestas Ante Honores, means "Honesty before Honour".
