Renfrewshire Council honoured the Saints with an open-top bus parade through the town centre before the team took to the outdoor stage in Bridge St.
DJs from Pulse FM were on hand to keep the crowd entertained before the fans got the chance to hear from their heroes, including captain Stephen McGinn, manager Jack Ross, chairman Gordon Scott and chief executive Tony Fitzpatrick.
Renfrewshire's Provost Lorraine Cameron said: "This was a wonderful occasion - they don't come around every year but Paisley knows how to party when we do. The great thing about being a one-team town is that Buddies can take over the streets and celebrate together.
"I come from a family of St Mirren supporters and remember going to Love St as a kid, and seeing some of the trophy wins of years gone by - so it was just wonderful to see a new generation of Paisley families get the chance to make their own memories tonight."
