Saltire's logo has appeared on the front of the Dons first team, U20s and Youth Academy kits for the past two seasons and this will continue for the next campaigns.
AFC Vice Chairman George Yule said: "We are delighted to be able to make this positive announcement ahead of the new season.
"Saltire's support has been fantastic and to be able to continue our relationship is very pleasing.
Established in 1986, and headquartered in Portlethen near Aberdeen, Saltire is a leading supplier of state-of-the-art drilling equipment to the global energy industry.
In 2008 Saltire established the 'Saltire in the Community' programme to support local initiatives to benefit young people.
It's through this that the company is involved with many sporting programmes, including AFC Youth, The Paul Lawrie Foundation, Saltire Energy Sports for Schools, University of Aberdeen Sporting Scholarships and Curling for Schools.
Mike Loggie, Chief Executive of Saltire Energy added: "We've really enjoyed our journey with AFC, both on and off the park. In particular participating in the development of the Club, at all levels within the local community has been fantastic.
"Saltire is delighted to be part of AFC's 'family' and we're looking forward to the coming season."
