The 26-year-old was a key performer in the Foxes’ title win last season and he has followed a number of his team-mates in committing his long-term future to the club.
The likes of Danny Drinkwater, Riyad Mahrez, Wes Morgan, Kasper Schmeichel and manager Claudio Ranieri have all done so, and now Albrighton has signed up until 2020.
“I just think there’s a really good feeling around the place,” he said.
“Everyone seems to want to stay at the club and I think that’s a massive credit to how far the club has come in the last few years.
“It’s exciting times for Leicester City Football Club and I want to be a part of that.”
Albrighton joined City from Aston Villa in the summer of 2014 on a free transfer which has proven to be an outstanding piece of business.
He has made 65 appearances for City, scoring four goals.
