The deal, which covers the 2008-09 season, replaces the FIA’s previous contract with Carnegie, the League’s sponsors for the past three years.
In a statement to the press, the FIA said: “Seeking a new sponsor for the IFA Premiership, the Irish Football Association had discussions with many companies over the course of the last six months and a number of offers were made to the Association.
“Whilst the IFA wanted to attract a valued and reputable company, it was also important to the Association that any potential sponsor would have a keen interest in sport and Northern Ireland. The Association was therefore thrilled to learn of JJB Sports' interest in the sponsorship opportunity."
JJB already supplies kit to the IFA and sponsors the Irish Cup.
