The following is a list of current franchised bus routes in Hong Kong, sorted according to bus companies. All current franchised bus routes are operated by air-conditioned buses only and fares are paid through flat fares. Note that Hong Kong Island, Kowloon and New Territories and Lantau Island have their own, separate route numbering systems.

These routes are not franchised routes, but the areas served by the LRT are a franchised area of the KCR Corporation / MTR Corporation Limited, and other bus companies were not allowed to run similar local routes in the northwestern New Territories until this restriction was lifted in 2006.
