Thomas Frank has signed a new five-year contract at Brentford until the summer of 2027.
The 49-year-old Danish manager only got one new business with the Bees in January, which was to last until the end of the 2024-25 season.
Frank led the club to promotion to the Premier League 18 months ago as they ended a 74-year exile from the top flight and then finished 13th last season.
Brentford are 10th in the table and will face Tottenham on December 26.
On his new contract, Frank said: “The warmth, support and kindness every time I meet a Bees fan has been incredible and it gives me extra energy to continue the job in the future.
“We attacked the Premier League in the first season and we are attacking it in our second season.
“I look forward to hopefully continuing our progress and creating more magical moments together.”
Frank took over as Brentford head coach in 2018 after leaving his role as assistant to Dean Smith, who left to take over as Aston Villa boss.
