The computing firm will provide technology for facilities at both Camp Nou and La Masia, while the company logo will be printed on the inside of the Blaugrana shirts
The Liga champions will be provided with the latest computing equipment for use within both Camp Nou and the La Masia training facilities as part of the lucrative new partnership.
The iconic Intel logo will also be printed on the inside of the Blaugrana shirt, a move which the club describes as "a pioneering initiative in the world of sports advertising."
"It is a huge satisfaction for Barcelona to be able to join forces and share the values of innovation and team-work with a company of such worldwide prestige as Intel," president Sandro Rosell was quoted as saying by the club's official website.
"It will mean much more than a financial sponsorship deal, as it will also help us to become one of the most technologically advanced clubs in the world.
"Intel is at the heart of computing, it works from within, and that is why our agreement is so innovative and pioneering in the world of sports sponsorship."
Barcelona will sport the new shirt for the first time during Saturday's Liga clash with Villarreal.
