Hemne Orkladal Billag or HOB was a Norwegian transport company based in Kyrksæterøra, Sør-Trøndelag.
By 1989 HOB had gotten into an economic mess with the wide range of activities the company was pursuing, including travel agencies, hotels, construction and fur farming.
Thams's Communications Aktieselskab (S&T), Kredittkassen, and Hemne Municipality went in with 8 million kr to save the company, and sold all non-transport related activities.
In 1996 and 1997 HOB purchased and/or merged with Mørelinjen (based in Sunndalsøra), Ålvundfjord Skysslag, Nordmøte Trafikkselskap (including the city bus in Kristiansand) and Molde Bilruter, with S&T in the end owning 50.1% of the company.
With this HOB controlled most of the transport in Uttrøndelag, Nordmøre and Romsdal, giving the company a large monopoly in the area.
