Leon McSweeney's first-half strike gave Hartlepool their third consecutive 1-0 win in League One as they overcame promotion-chasing Huddersfield.
the side with the tightest away defence in division secured another shut-out and have now conceded only six times in 11 games away from Victoria Park this season.
McSweeney put Mick Wadsworth's side in front just before the break from close range, tapping home Evan Horwood's cross at the back post.
Substitute Armann Bjornsson should have made it 2-0 but he somehow blazed the ball over the crossbar from close range.
Pools are only three points off third-placed Town with a game in hand, and a point outside the play-off zone.
