GoByBus (previously known as Säfflebussen) is a Swedish long distance bus company which runs regular services between the country's major cities. It also offers services to other (mainly neighbouring) countries, with destinations including Hamburg (Germany), Copenhagen (Denmark), Oslo and Trondheim (Norway).
Other bus services that run similar routes include the E6 Express from NOR-WAY Bussekspress (Oslo-Sarpsborg-Göteborg and beyond) and Swebus Express.
Before March 2006 GoByBus was known as Säfflebussen, but when acquired by the Norwegian bus company Nettbuss the name was changed.
