The European champions will take on the Serie A giants at the home of Scottish Rugby on July 28.
The stadium, which officially holds 67,144 people, has hosted football fixtures in recent years, most notably the Betfred Cup semi-final between Celtic and Hearts in October last year.
This game attracted 61,161 spectators, the largest crowd for a Scottish football match for almost two decades.
The same two clubs have also played some European fixtures at the Capital stadium, while the Jambos also fulfilled some league fixtures during the redevelopment of the main stand at their Tynecastle Park home.
Catalan giants Barcelona have also taken on Hibs and Hearts in pre-season friendlies at Murrayfield in the past.
