The Spaniard joined Arsenal in 2019 and was heading into the final year of his deal before agreeing new terms ahead of the north London derby on Sunday, September 15th.
Arteta has ushered in a new age of success at the Emirates, winning the FA Cup and Community Shield during his tenure and finishing second in back-to-back Premier League seasons.
His side have been the closest challengers to Manchester City over the past two years and are gearing up for another title battle in the 2024/25 season.
Arteta, who played 150 times for Arsenal and captained the side, expressed his pride in signing a new deal.
"I feel extremely proud, very excited and am looking forward to what is coming next.
"I'm proud to be where I am and have the relationships that I have with everyone at the club.
"I feel extremely lucky to work every single day with good people and the ambition we have here. I feel very inspired, I feel challenged, I feel supported and I want to do much more than what we've already done together."
The Gunners have enjoyed a solid start to the current campaign, with two wins and a draw from their opening three fixtures.
Arsenal are next in action against rivals Tottenham Hotspur before a trip to Atalanta in the Champions League and a visit to City the following weekend.
