Ipswich beat arch rivals Norwich for the first time in 16 years as Jaden Philogene's superb long-range strike inspired a 3-1 win in the Championship clash on Sunday.
Cedric Kipre's opener for Ipswich was cancelled out by Norwich's Oscar Schwartau at Portman Road.
Philogene restored Ipswich's lead with his thunderous drive from 30 yards and substitute Jack Clarke bagged the third goal as Ipswich bolstered their bid for promotion to the Premier League.
Kieran McKenna's side now sit in ninth place, just two points adrift of the play-off places, as they look to atone for last season's relegation.
Ipswich had gone 14 games without a win over Norwich and McKenna was relieved to finally end that painful streak.
"The big thing with a derby match, especially with the narrative around it and the record is the outcome, so it's a great win, it's a convincing win. We were good value for the 3-1 to be honest," he said.
"Performance-wise, our execution was mixed. I really liked our intent. We got from the middle of League One to the Premier League for being brave and we came into the game with that intent today.
"It's a really new group, playing with the tension of getting some momentum together. Some big goals, incredible by Jaden Philogene, and we could have got more."
Norwich remain just above the relegation zone in 19th place after their first loss in the 'Old Farm' showdown since a 3-2 defeat in April 2009.
"To concede a poor goal from our perspective, turning it over in midfield, obviously a great finish, but the timing of the goal kills it when we could have been going in 1-1 at half-time," Norwich boss Liam Manning said.
"The third goal is where we're at at the minute, giving the ball away. You can have all the plans and tactics but you have to have the foundations and basics in place. We just don't seem to do that to other teams."
