Match ends, Huddersfield Town 1, West Ham United 1.
Huddersfield manager David Wagner felt his side "had no luck" as West Ham's Felipe Anderson scored a late equaliser to prevent the Terriers claiming their second win in six days.
Still buoyant from Monday's victory over Fulham, Wagner's men started brightly and Alex Pritchard opened the scoring with just their second goal at home this season - and the first scored by a Huddersfield player.
The hosts hit the woodwork twice and Wagner believed they should have had a penalty for a foul on defender Mathias Jorgensen, nicknamed Zanka, before the break.
The Huddersfield boss said: "We hit the post and bar again, and we had another big decision against us when Zanka got fouled. It was a penalty from my point of view and, again, we had no luck in the game."
But West Ham had the better of the second half and although Anderson drew the Hammers level, they were unable to follow up last week's win over Burnley with another victory.
The Hammers remain 13th in the Premier League after missing the chance to gain back-to-back league wins for the first time since January 2017, while Huddersfield are second-bottom after Cardiff's win over Brighton earlier.
The Terriers will now be without Chris Lowe for several weeks as the German midfielder was carried off after an injury late in the first half.
Wagner added: "He looks to have a shoulder ligament injury. We need to see if he needs surgery, but he will miss a few weeks now for sure."
Terriers show stomach for a fight
It took six games for Huddersfield to score at home this season but the Terriers carried that momentum from Monday into Saturday's game.
They won a second-minute corner from which Steve Mounie headed Aaron Mooy's delivery goalwards, only to see Lukasz Fabianski tip it against the crossbar.
West Ham then gave the ball away in their own half and Pritchard played a one-two with Jonathan Hogg before dragging a left-footed shot towards goal, but it had enough power to creep into the bottom corner.
The Terriers deserved their half-time lead and they could have been more comfortable as Philip Billing's left-wing cross drifted over Fabianski and hit the inside of the far post before bouncing on the goalline.
Mounie was again denied by Fabianski after being put clean through by Pritchard, and in the second half Huddersfield had to rely on the defensive resolve that served them so well last term.
Anderson may have struck eventually, denying the Terriers their first back-to-back league wins since February, but four points in a week has more than doubled their tally.
Hammers consistently inconsistent
In this fixture last season, West Ham showed just what they are capable of by cruising to a 4-1 victory and, after Manuel Pellegrini's appointment in the summer, they have displayed their potential again with wins over Everton and Manchester United before brushing aside Burnley last week.
But Pellegrini's biggest challenge is getting that level of performance out of his side on a regular basis - and for 90 minutes - as it needed a much-improved second-half showing to secure a draw.
A lively start could have seen the Hammers strike as a break resulted in Marko Arnautovic forcing home goalkeeper Jonas Lossl to turn his shot wide.
But moments later Anderson's pass put Declan Rice under pressure and Huddersfield pounced to take full advantage, and more loose play by the visitors in their own half handed Mounie his second chance of the game.
In last season's trip here, West Ham scored three goals in 16 minutes at the start of the second half and they almost struck just after the restart again as Javier Hernandez, who replaced Grady Diangana at half-time, had a close-range shot blocked by Lossl before heading the rebound over.
Pedro Obiang had glancing a header wide from a Robert Snodgrass corner before Anderson burst down the left wing and passed for Snodgrass to cross into the box.
The Hammers had two shots blocked before Anderson, who by now had drifted into the box, swept in his third goal in two games from 12 yards, and they nearly won it as Issa Diop had a header cleared off the line by Mooy from a Snodgrass corner.
'I really can see the positives' - what they said
Huddersfield manager David Wagner said: "The frustration is there, after the first half when we were very strong. In the second half I have to be honest, West Ham had opportunities as well. But in the last five minutes we were the team that wanted to push for the win.
"The good thing is four points in a week. I really can see the positives. We'll take this result even if I think we deserved more."
West Ham manager Manuel Pellegrini said: "We didn't play well in the first half after their goal. You have to fight for every ball when you come here, they play with a great intensity and aggression. We also kept the ball too much in our own half, this is a team that aggressively presses you.
"In second half we improved a little bit more, we created chances and we got the goal. But if you review the 90 minutes, the draw was the result that both teams deserved."
