Sir Kai Ho, CMG, JP, MRCS (Chinese: ??; 21 March 1859 – 21 July 1914), better known as Sir Kai Ho Kai, born Ho Shan-kai (Chinese: ???), 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 student 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.
