The former Munster and Ireland star (37) and the marketing professional exchanged vows in front of friends and family in Marbella.
The newlyweds enjoyed a fitting outdoor ceremony in the mountain village of Benahavis, with famous friends in attendance such as model Nadia Forde and his former Ireland teammates Donncha O'Callaghan and Paul O'Connell.
They decided against bridesmaids and groomsmen, instead opting to keep it a small affair with select guests.
Peter and Debbie have been based in Bath for the last two years and will be moving to Sale, where Stringer has signed a new contract, on their return to the UK.
They decided to postpone their honeymoon until later this year and will be spending the rest of the week in Spain basking in newlywed bliss with their loves ones.
Stringer said yesterday he was happy to let his other half soak up the spotlight on their big day.
"I’m going to deflect a lot of it on to Debbie - it’s all about her, I’ll try fade into the background as much as I can,” he told Ray D'Arcy on RTE Radio One.
"Debbie looks amazing no matter what she wears, I’m looking forward to seeing her on the day."
