With more than 1,000 competitive appearances, he has played for United more than any other player. Having won 13 league titles, four FA Cups and two UEFA Champions League trophies, he is also the most decorated player in the history of English football.
On Thursday, new Manchester United manager David Moyes announced that Giggs has been named player-coach with immediate effect.
"His career is an example to any aspiring young player, and I'm sure that both he and the players will benefit from his new role," Moyes said, per CNN.
As Giggs embarks on this new phase of his footballing life, we decided to pick 10 goals to sum up his career to date. Enjoy, and be sure to add any special memories to the comments.
Ryan Giggs scored his first senior goal for Manchester United on Sept. 7, 1991, nearly 22 years ago. The opponent was Norwich.
At the time of the goal, Giggs' future teammate Wayne Rooney was six years old. Manager Sir Alex Ferguson was 49.
Giggs' best goal came in United's memorable 2-1 victory over Arsenal in the 1999 FA Cup semifinal replay. If you've seen it, you'll never forget the mazy running, superb control and astonishing finish.
Besides being beautiful, this one was also important. United went on to win the treble that season, and Giggs' goal kept the dream alive at a critical juncture.
Another spellbinding run produced another memorable goal for Giggs against Juventus in a February 2002 UEFA Champions League match.
Taking possession of the ball near midfield, Giggs blew past Juventus' defense and finished with cool ease as United raced to a 3-0 victory.
Just 18 at the time, Giggs hinted at his vast potential with this classic 1992 goal against Tottenham in the Premier League.
After pouncing on Dean Austin's slip, Giggs used his first touch to beat Austin, his second to nutmeg Jason Cundy, his third to round goalkeeper Ian Walker and his fourth to finish with authority from a tight angle.
It was simply jaw-dropping.
On the way to that PFA Player of the Year award in 2009, Giggs thrilled fans with some classic wing play like the goal above.
This one came against West Ham in February 2009 and displayed Giggs at his classic best.
Overshadowed as a free-kick taker by David Beckham and Cristiano Ronaldo, Giggs has scored a few dead-ball beauties of his own.
This one against Bolton at the beginning of the 2003-04 season ranks up there with his best.
Outclassed by Juventus in the Champions League the previous season, United broke through and came of age in Europe with a 3-2 win over the Italian giants in October 1997.
Giggs scored the third late in the match, and it was a spectacular strike worthy of the symbolic occasion.
The previous spring, Giggs was in top form as Manchester United routed Porto 4-0 in the first leg of the Champions League quarterfinals.
Giggs finished a flowing move for the team's third goal, capping a night on which he was unplayable.
In September 2011, Giggs extended his own record as the Champions League's oldest goalscorer with this strike against Benfica.
Typically for Giggs, it was another stunner.
