Brighton boss Fabian Hürzeler has agreed a new three-year contract until June 2029.
The 33-year-old German, who joined Brighton at the start of last season, has guided his side to eighth in the Premier League, at the cusp of European qualification.
"I absolutely love working for this club and living in the city and I am delighted to have agreed a new contract," Hürzeler said.
"To have this long-term commitment from the club is an honour and one which only reinforces my desire to succeed in delivering on our shared long-term vision.
"From the beginning our focus has always been on forging an identity, developing the team, challenging the establishment and pushing our standards every day.
"I'm proud of what we have done so far and even more excited about what is still to come."
Brighton have three matches remaining this season, starting with a visit from Wolves on Saturday.
Brighton chairman Tony Bloom said: "Since his appointment, Fabian has continued the progress the club has made in recent seasons with consistent on-pitch performances and he has developed a clear playing identity.
