The agreement represents the Japanese manufacturer's largest ever sponsorship deal and establishes Nissan as an official partner worldwide from 2014/15 to and including the 2017/18 seasons.
"Innovating to excite is what Nissan does, and as partners with UEFA we are looking to introduce new ways in which to enrich the UEFA Champions League experience," said Roel de Vries, Corporate Vice President and Global Head of Marketing and Communications for Nissan.
"Europe's most prestigious football competition will be an important global platform for Nissan, and our aim is to show fans all over the world the excitement of both football and our cars. Both are created by amazing people who have a passion for what they do."
As an official partner, Nissan will have extensive rights to the matches, pre-match training sessions, content, media, hospitality, events and the Champions League Final.
Jeanne McGann, Head of Marketing & Communications in Nissan Ireland, said: "We're very excited to be part of this initiative and the opportunities it provides; we look forward to an interesting four years ahead."
The UEFA Champions League reaches over 4 billion TV viewers a season, and the deal will bring Nissan to new audiences and keep the brand at the fore over the course of the European football calendar.
