The three year, seven figure deal will see the energy company involved in a major partnership that extends beyond the first team squad.
Commenting on the deal, Pittodrie Vice Chairman George Yule said: "We are absolutely delighted to have secured this partnership with Saltire Energy, an organisation that already enjoys a close relationship with the club through supporting of several initiatives over the years.
"In addition to Saltire's involvement with the senior squads, they are also going to support all of our youth development teams which of course are where many first team stars of the future can currently be found.
"I would also like to take this opportunity to thank Terry Allan and Team Recruitment for their fantastic support over the past six years, which has been very much appreciated."
Saltire Energy established the 'Saltire in the Community' programme in 2008 to support local initiatives that would primarily benefit young people.
Through this, the company is already involved with many sporting programmes, such as AFC Youth, The Paul Lawrie Foundation, Saltire Energy Sports for Schools, University of Aberdeen Sporting Scholarships and Curling for Schools.
