China Motor Bus Company Ltd. (HKSE: 0026 (http://www.hkex.com.hk/invest/index.asp?id=company/quote_page_e.asp?WidCoID=0026&WidCoAbbName=&Month=&langcode=e)) , was the first motor bus company in Hong Kong. In 1933 CMB was granted a franchise (read: monopoly) by the Government of Hong Kong to operate routes on Hong Kong Island.

CMB buses were traditionally painted with a buff upper body and a blue lower body. Over the years CMB had developed a reputation of having outdated ethos and poor services, culminated in its eventual loss of the franchise in 1998, which were taken over by New World First Bus.

It currently provides hire service and real estate development, operating one route between North Point MTR station and North Point government offices.
