The Maggie May singer and Boyle will be performing at the opening ceremony at Celtic Park on 23 July in front of 40,000 spectators, as well as an expected global television audience of more than one billion.
Joining them will be classical musician and Classical Brit Award winner Nicola Benedetti, Glasgow singer-songwriter Amy MacDonald and Julie Fowlis, who found global recognition through the songs she performed in the Oscar, Golden Globe and Bafta-winning film Brave.
David Zolkwer, head of ceremonies and artistic director, said: "We’re so thrilled that Glasgow’s opening ceremony is going to feature such an extraordinary line-up of world-class talent - all with such warm ties to Scotland and the city. It’s going to be a fantastic party - full of Scottish heart and soul."
David Grevemberg, chief executive of Glasgow 2014, added: "We have always said that the opening ceremony will present Glasgow and Scotland to a global audience. But when we get to welcome an iconic talent like Rod Stewart it takes the excitement and anticipation for the opening ceremony to a whole new level.
"We will also be welcoming internationally renowned and acclaimed artists Susan Boyle, Nicola Benedetti, Amy MacDonald and Julie Fowlis on the night. They will join the thousands of people who are part of our cast for a unique celebration of the host city and nation which will not only welcome the athletes to Glasgow for the Commonwealth Games, but which will also be seen and enjoyed across the world."
