Nahki Wells scored a late winner as Huddersfield fought back to end Bolton’s eight-match unbeaten run.
Darren Pratley gave the visitors the lead after 41 seconds, crashing the ball home off the underside of the crossbar from the edge of the area.
Keeper Andy Lonergan made a series of saves before Jacob Butterfield levelled with a half-volley.
Substitute Wells then coolly finished under Lonergan after Emile Heskey had a Bolton effort ruled out for offside.
Former England striker Heskey was again used as a substitute after scoring on his debut for the Trotters on Boxing Day, but his introduction could not stop Bolton slipping to a first defeat since 31 October.
Huddersfield’s first victory in four matches sees them move up to 18th in the Championship table, while Bolton drop one spot to 15th.
Trotters midfielder Pratley punished the Terriers for their inability to decisively clear the danger from an early free-kick, calmly bringing the ball down on his chest before giving Bolton the ideal start with a thumping finish.
Butterfield went close to hitting back soon after, testing Lonergan from close range, while James Vaughan and Harry Bunn also called the visiting keeper into action.
Alex Smithies kept Eidur Gudjohnsen out at the other end before Jonathan Hogg found Butterfield in space to rifle in a deserved equaliser.
Butterfield continued to trouble Bolton and had a weak follow-up shot scrambled away by Lonergan after the keeper had kept Vaughan at bay.
Heskey looked to have put Bolton 2-1 up but, after poking the ball past Smithies, his effort was ruled out for offside.
Lonergan tipped a Jack Robinson shot over the bar before Wells won it with a low finish after racing on to a Hogg through ball.
