香港，九龍巴士(一九三三)
Kowloon Motor Bus (KMB) is the largest public bus operator in Hong Kong with a fleet of 3,800 buses. Established in 1933, it outlasted China Motor Bus (est. 1924) to become the oldest franchised bus operator in Hong Kong. KMB operates largely in Kowloon and New Territories.

KMB operates a bus fleet consisting of a diverse range of bus models and configurations. A majority of KMB's fleet is made up of double-decker buses. There are four major liveries used by KMB:
- cream (non air-conditioned bus, phased out in 2012)
- white (air-conditioned, generally non-WAB bus)
- gold (air-conditioned, wheelchair accessible bus until 2018)
- red (air-conditioned, wheelchair accessible bus from 2019)

Kowloon Motor Bus bears many similarities with SBS Transit in terms of bus fleet and operations (before the introduction of competitive bus tendering in Singapore), and hence is often used as a comparison by Singapore bus enthusiasts.
