The Kowloon Motor Bus Company (1933) Limited (KMB; Chinese: 九龍巴士(1933)有限公司), a company of the Transport International Holdings Limited, is the largest franchised bus operators in Hong Kong, and one of the largest privately owned public bus operators in the world. For its franchised service in Hong Kong, KMB operates a fleet consisting of about 4,300 buses on 420 routes and employs a staff of over 13,000.
KMB was founded on 13 April 1933 as a result of the reformation of public transport by the then-British colonial government of Hong Kong. Before the reformation, there were several independent bus operators working on both sides of the Victoria Harbour.
