Local and regional bus services are a large part of public transport in the Helsinki region. HSL bus services include internal services in Helsinki, Espoo, Kauniainen, Vantaa, Kerava, Kirkkonummi, Sipoo, Siuntio and Tuusula and regional services between them.

Since 2010, the planning and timetabling of these bus routes have been done by Helsinki Region Transport, an organisation to which the aforementioned municipalities belong. Prior to HSL's inception, Helsinki's internal lines were the responsibility of Helsinki City Transport, with all other bus services being organised by YTV, HSL's predecessor.
