Veteraanikuorma-autoseura ry, known as Vetku, is a nationwide Finnish enthusiast association founded in 1987. It works to preserve vintage trucks and other commercial vehicles, along with the traditions, history and knowledge connected to them. The association collects and archives relevant materials and produces publications and audiovisual recordings about truck heritage, vehicle restoration and transport culture.

A prominent part of Vetku’s activities is its popular “keikat”: touring events held around Finland three times a year, alongside other gatherings and appearances at vehicle events and exhibitions. Members can explore the association’s historical resources, including material on Sisu and Vanaja vehicles, vehicle presentations, publications and a photographic gallery. Vetku also provides a discussion forum with a marketplace for buying and selling related items, and offers association merchandise.

Founded to bring enthusiasts together, Vetku had 1,017 members as of August 2025, including 116 supporting companies. It is the largest independent member association within SAHK, Finland’s national federation for historic vehicles. Membership is open to interested individuals, with a separate supporting membership option for companies.
