Huddersfield have waited 40 years to beat the Clarets but ended that hoodoo at the 14th attempt as a second away defeat in the space of five days put a dampener on Burnley's start to the season.
Goals in each half from Joel Lynch and super striker Jordan Rhodes gave Huddersfield their first victory since their Championship return.
And with little prospect of a response from a below par Burnley, boss Eddie Howe was left with food for thought just a week on from out-playing Bolton in such style.
With no Martin Paterson and Danny Ings, the Clarets again looked short of attacking options and with a week to go until the transfer deadline Howe may have to dip into his contacts book - if circumstances allow - or keep his fingers crossed that Paterson's impending return from injury will be a permanent one.
In a lively start the Clarets - backed by an excellent following of over 3,000 - had actually created the first chance for Dean Marney following good work by Ross Wallace, only for the midfielder's shot to be deflected over the top.
But despite their indifferent record since promotion, Town didn't look short of confidence as they went in front with just six minutes gone.
The loan signing of James Vaughan pepped up the Terriers' attack and after his shot on the break was deflected for a corner a header from Lynch was judged to have crossed the line before Joseph Mills hacked clear.
Huddersfield had previously relied heavily on Rhodes for their goals and the prolific striker came alive after quarter of an hour when he headed a Sean Scannell cross against the bar.
The Clarets also did themselves few favours when over-playing from the back, Vaughan twice almost punishing Jason Shackell and Lee Grant.
And even though Grant made amends with a sharp save from another Rhodes header the Clarets struggled to get anything going the other way.
The front pair of Charlie Austin and Sam Vokes saw little of the ball and with the home side always a threat as they went forward - Adam Clayton sending a deflected shot onto the roof of the net -Burnley were probably happy to be heading for the break just a goal down and with the chance to re-group.
Howe's team-talk might have been different had an effort from David Edgar, deflected off Austin, not been disallowed for off-side in first-half stoppage time but as it is he sent out the same side to start the second half, presumably with the message to raise the tempo and give the home side something to think about.
The response was briefly positive but the Clarets still struggled to create a meaningful chance and with 57 minutes gone their task was made doubly difficult as Huddersfield went 2-0 up.
Rhodes' work outside the penalty area left a bit to be desired at times but Town's talisman comes alive when he sees the whites of the post and when Burnley failed to deal with a ball into the box, the 22-year-old picked up the pieces, composed himself and smashed a right-foot shot past Grant.
Howe reacted by sending on Michael Duff and changing the Clarets' formation to push Mills and Kieran Trippier into more advanced positions.
But the Clarets still looked lightweight up front with Austin carrying the burden as he headed a Trippier cross onto the roof of the net from no more than a half chance.
The introduction of Keith Treacy with 17 minutes to go for his first appearance of the season was a final throw of the dice but it was a free-kick from Wallace with 11 minutes to go that was the nearest the Clarets' came to pulling one back and at least making the Terriers sweat.
