Will Keane has now scored two goals in seven Championship appearances for Ipswich this season.
Ipswich Town striker Will Keane grabbed a late equaliser to deny Stoke City a first win in five matches in the Championship.
James McClean opened the scoring for the visitors after a mix-up in the hosts' defence saw Jonas Knudsen head a backpass beyond goalkeeper Bartosz Bialkowski, giving the Republic of Ireland international an easy tap-in.
Alan Judge nearly equalised for Paul Lambert's side straight after the restart as his free-kick from 25 yards was tipped on to the crossbar by Jack Butland.
But bottom of the table Ipswich struck in the first minute of injury time as Keane nodded home Judge's inswinging corner.
The Potters started the brighter and nearly opened the scoring in the third minute with Bialkowski doing well to tip over Tom Edwards' deflected cross.
Striker Sam Vokes could have put Stoke ahead after 35 minutes, heading Tom Ince's cross over from 12 yards, and midfielder Joe Allen shot narrowly over after good play by Sam Clucas.

Going into the game, no Championship side had taken fewer points - 10, level with Bolton - than Ipswich since manager Paul Lambert's first league match in charge, but after falling behind, his side dominated proceedings.
Judge twice went close for Town late in the first half before seeing his free-kick diverted on to the bar by Butland after 52 minutes.
With 10 minutes to go, Gwion Edwards' cross found Kayden Jackson but the striker was unable to direct his effort on target.
Ipswich are nine points from safety at the bottom of the table, while Stoke stay in 17th.
Ipswich Town boss Paul Lambert:
"I thought we played well. We're up against a team that have spent an incredible amount of money with a strong squad.
"I thought they scored against the run of the play, there was nothing in it. It was a mistake.
"Second half we were relentless, the atmosphere in this stadium was bouncing and it's another massive point."
Stoke City manager Nathan Jones told BBC Radio Stoke:
"It's disappointing because I couldn't really see us conceding. And to concede in the manner we did was doubly disappointing.
"When the ball came in, we've got enough people in there to be able to head it - that's how you see out a game. Someone gets a head on it, they don't score and we win the game.
"We just need that killer instinct to see out the game, that bit of knowhow. We created enough chances that would have made that goal irrelevant at the end."
