Catalans Dragons scored two tries in the last nine minutes to end their six-match losing run and break Hull's hearts in a dramatic Betfred Super League clash in Perpignan.
The Dragons were heading for another defeat when Hull winger Nick Rawsthorne scored his second try of the match on 67 minutes to give his side an 18-11 lead.
However, the Catalans finished strongly, with Fouad Yaha and Tony Gigot touching down kicks from scrum-half Luke Walsh to secure a 23-18 victory in the first home match under caretaker coaches Jerome Guisset and Michael Monaghan.
The victory enabled the French club to climb out of the bottom four at the expense of Warrington Wolves, while Hull drop out of the top four after a third successive defeat - their misery compounded by the late dismissal of prop Liam Watts for a high tackle on Dragons captain Remi Casty.
Catalans' victory came just three weeks after a 62-0 Challenge Cup mauling by the Black and Whites.

Hull coach Lee Radford told the Hull Daily Mail: "Our effort was fantastic but our smarts, say no more. We had an ample amount of chances to win that game but we didn't.
"I applaud the effort but I'm so frustrated with how it panned out. There was certainly an improvement from when we lost to St Helens and the Leigh game on Friday.
"We had nothing to lose in a way because their starting 13 was almost out there today, only Justin Horo was missing. You look at ours and we had guys missing and some patched up.
"I don't think anyone will be back for Wigan on Saturday. We'll assess all that on Thursday before the match."
