A Night Bus is a bus service which operates through the night time hours. Many cities operate such services, in substitution for either ordinary daytime bus services or metro/subway rail services. Night bus service is much more limited than daytime bus service, there are fewer lines and the buses run less frequently. In some cities such services have their own fare structure, in others the standard bus fare structure applies.

Cities with night bus services

• Dublin, Ireland: See Dublin article.
• London, United Kingdom: See Buses in London article.
• San Francisco, California, United States: See San Francisco Municipal Railway article.

Withdrawn Services

• Colchester;U.K, used to have one for clubbers but this was withdrawn due to losses. It would have been profitable if only run on Friday and Saturday nights. It is hoped the service will resume with a revised timetable.

The night bus in literature

The London night bus was the inspiration for J. K. Rowling's Knight Bus.
