Nottingham Forest announced that Victor Chandler is to continue to be the club's official sponsor until the summer of 2012.
The online bookmaker and gaming company has agreed a new two-year deal after a successful first season as the club's sponsor.
Forest's Chief Executive Mark Arthur said: "We are proud of our record of forging strong associations with our principle sponsors and delivering success for them.
"And we are delighted Victor Chandler has agreed to extend the sponsorship agreement for a further two years."
Victor Chandler, Chairman of the company that bears his name, added: "I am delighted to have reached an agreement to continue sponsoring Nottingham Forest for a further two seasons.
"This season has been a huge success and I am confident the team will secure promotion to the Premier League. The global television coverage of the Premier League offers worldwide media opportunities and will benefit our Far East business particularly."
Victor Chandler currently rate Forest as an 8/1 shot to win the Coca-Cola Championship this season and Evens to gain promotion to the Premier League.
Robert Earnshaw and Dexter Blackstock are both priced up at 5/6 to finish this season as Forest's top league goal-scorer.
Victor Chandler is hoping Forest gain promotion to the Premier League, although not as Champions as this would cost Chandler in the region of £6m following his pre-season promotion pledge to season ticket holders to pay for next season's renewals should they win the league.
Viv Anderson, Forest Legend and now Victor Chandler's football ambassador, commented: "Victor thought he was offering a safe bet at the start of the season but the turnaround with Forest has been amazing.
"Billy Davies has built a tough, well organised side and even if they miss out on automatic promotion they will enter the play-offs as strong favourites to be promoted."
