The 34-year-old had not played for a club since leaving Leicester at the end of the 2022-23 season, when the Foxes were relegated from the Premier League.
Bertrand started his career at Gillingham, before moving to Chelsea's youth set-up and then spending time on loan with the likes of Norwich, Reading and Nottingham Forest.
The defender made 57 first-team appearances for Chelsea, including the 2012 Champions League final against Bayern Munich, which the Blues won on penalties.
After an initial loan spell, Bertrand made a permanent switch to Southampton during February 2015, playing more than 200 games for the Saints before moving to Leicester on a free transfer in the summer of 2021.
"It's been a little while, but I get asked a lot of questions, 'when are you coming back, what are you doing?', Bertrand said on Sky Sports. "So, just to make that official I am retiring and very much looking forward to the next steps."
Bertrand won 19 senior England caps and was part of Roy Hodgson's squad for Euro 2016.
