Paul Marcon's dramatic late try stunned reigning champions St Helens and gave newcomers Toulouse their first ever Super League victory.
The France winger touched down three minutes from time to snatch the win.
Saints conceded in the opening seconds of the game before fighting back to lead 18-12.
But Chris Hankinson's converted try and Marcon's late effort saw Toulouse over the line and handed the league leaders their first defeat this season.
The league's bottom side rocked Saints from the kick-off, winning the ball back and moving it swiftly out to the left, where Scotland international Matty Russell touched down in the corner.
