Beckham made 115 appearances for England and 394 for Manchester United, winning six Premier League titles and the Champions League.
Here, in his statement released today, Beckham talks about his decision to retire from playing.
"I'm thankful to PSG for giving me the opportunity to continue but I feel now is the right time to finish my career, playing at the highest level.
"If you had told me as a young boy I would have played for and won trophies with my boyhood club Manchester United, proudly captained and played for my country over one hundred times and lined up for some of the biggest clubs in the world, I would have told you it was a fantasy. I'm fortunate to have realised those dreams.
"To this day, one of my proudest achievements is captaining my country. I knew every time I wore the Three Lions shirt, I was not only following in a long line of great players, I was also representing every fan that cared passionately about their country. I'm honoured to represent England both on and off the pitch.
"I wouldn't have achieved what I have done today without my family. I'm grateful for my parents' sacrifice, which made me realise my dreams. I owe everything to Victoria and the kids, who have given me the inspiration and support to play at the highest level for such a long period. I also want to thank Simon Fuller and his team for their continued support.
"I want to thank all my team-mates, the great managers that I had the pleasure of learning from. I also want to thank the fans who have all supported me and given me the strength to succeed.
"Nothing will ever completely replace playing the game I love, however I feel like I'm starting a new adventure and I'm genuinely excited about what lies ahead. I'm fortunate to have been given many opportunities throughout my career and now I feel it's my time to give back."
The midfielder made his England debut against Moldova in 1996 and captained the side from 2000 to 2006, making his 115th and final England appearance in a 3-0 win over Belarus in 2009.
Including PSG's recent Ligue 1 title win, Beckham has won 19 trophies - 10 of them league titles - in a playing career spanning 20 years, and is the only English player to win championships in four countries.
