In 2002 Scott stunned the field with rounds of 67, 66, 69, and 67, to finish a massive 19-under par on the challenging 7,374-yard Doha championship course in a remarkable performance that saw him win by six shots from England's Nick Dougherty and Frenchman Jean Francois Remesy.
"It's been a long time since I won in Qatar back in 2002 and a lot has happened to me since then but I am delighted to be heading back to Doha for the Commercialbank Qatar Masters," Scott said.
"Playing the US, European and Australasian Tours has introduced me to so many incredible destinations, and every year I look forward to the places these tours will take me and the great challenges that lie ahead.
"I haven't been there for a few years but I do enjoy playing there. It's a fascinating place."
Adam Scott comments on Doha, the venue for the Qatar Masters
"Doha is one of them - relaxing and always with great weather. Just the kind of place you'd go on a holiday. I haven't been there for a few years but I do enjoy playing there. It's a fascinating place."
The 27 year-old Australian, now established as a truly international world-class golfer, claimed his second title on the PGA European Tour International Schedule with his 2002 Qatar win, and since then has gone on to win some of golf's biggest titles.
At the age of 23 years, eight months and 12 days Scott became the youngest winner of the PGA Tour's Players Championship in 2004 at Sawgrass, an event considered by many to be the game's fifth Major.
Golf growing in Qatar
"Adam Scott is without doubt one of the finest and most charismatic players in world golf," said Andrew Stevens, Group CEO of tournament title sponsors Commercialbank.
"He was absolutely sensational when he played and won in Qatar in 2002, despite some seriously windy conditions.
"Since then he has become a real international player with tournament victories in Singapore, Europe and the USA so it's a real pleasure to have him agree to return to the scene of one of his first international victories."
Scott's confirmation that he will return to try and become the first man in the tournament's history to win the title on more than one occasion was also welcomed by Hassan Al Nuami, Qatar Golf Association president.
"Over the years, as this tournament has grown, we've seen how the world's best players want to play in Doha," Al Nuami said.
"This is a huge vote of confidence in both the tournament and Qatar."
The Qatar Masters, fully sanctioned by the PGA European Tour, was won in 2007 by South African Retief Goosen and is again expected to feature a line-up of some of the biggest names in world golf.
The 2008 tournament will be played from January 24 to 27.
