The Cottagers announced the capture of the 32-year-old on a three-year contract on Monday night, paying an undisclosed fee for the England midfielder's services.
Parker will meet his new team-mates at training today and takes with him a wealth of experience at the top level.
He has won 18 caps for England - captaining them in 2012 - and has over 300 Premier League appearances to his credit.
"I'm delighted to be joining Fulham and I'm looking forward to meeting my new team-mates at training," he told Fulham's official website.
"Fulham is an established Premier League club and I look forward to trying to help the team progress even further over the next three years."
Parker makes a short hop across London in order to join Martin Jol's men and Fulham will be the fifth capital club he has played for.
He started his career at Charlton, before moving to Chelsea. He then then headed to Newcastle, but returned 'home' for a successful spell with West Ham during which he was named as the Football Writers' Association Player of the Year.
The Hammers' relegation from the Premier League paved the way for Parker to move to Spurs and it was while at White Hart Lane that he was asked to captain England in a friendly against Holland.
He started every group match at Euro 2012 and arrives at Craven Cottage as a stellar name.
"I'm delighted that Scott has joined us," manager Jol said.
"He's a midfielder who works tirelessly for his team and is a fantastic player both on and off the ball.
"It is wonderful to see a player of his stature playing for Fulham Football Club as he has shown his qualities in the Premier League and for the England team for many years.
"I'm happy that he's here and joins us for training ahead of our first home match of the season."
