Sir Kai Ho, CMG, JP, MRCS, better known as Sir Kai Ho Kai, born Ho Shan-kai, was a Hong Kong barrister, physician and essayist in Colonial Hong Kong. He played a key role in the relationship between the Hong Kong local community and the British colonial government. He is remembered as a supporter of the Reform Movement and as a teacher of Sun Yat-sen, who would become the founding father of the Republic of China. Kai Tak Airport, Hong Kong, was named after him and his son-in-law Au Tak, though he died in 1914, long before the idea of an aerodrome was first mentioned in 1925.

Kai Tak Airport (IATA: HKG, ICAO: VHHH) was an international airport of Hong Kong from 1925 until 1998. Officially known as Hong Kong International Airport from 1954 to 6 July 1998, it is often referred to as Hong Kong International Airport, Kai Tak, or simply Kai Tak and Kai Tak International Airport, to distinguish it from its successor, Chek Lap Kok International Airport, built on reclaimed and levelled land around the islands of Chek Lap Kok and Lam Chau, 30 kilometres (19 mi) to the west.
