The 65-year-old broke the news during a live interview on Sky Sports News.
Pulis was last in a job in 2020 when he was at Sheffield Wednesday, although his spell only lasted ten games.
The reason behind his retirement was so he could spend more time with his family as well as playing golf.
He said: “I’m 65 now. I had a really good run at it, management has passed me by now.
“I’m quite happy to help people, quite happy to give a little bit of advice here and there.
“I’ve always based my home down in Bournemouth.
“I had three wonderful children and never spent enough time with them but I’ve got seven grandchildren now.
“It’s lovely to see them and be able to go out and watch the boys play football, and we have two in America and we visit them as much as possible.
“I play a bit of golf here and there, nice and relaxed.”
HOW TO GET FREE BETS ON FOOTBALL
Pulis was a player before he was took up management, his first job was at Bournemouth following Harry Redknapp‘s move to West Ham in 1992.
He would then go on to take charge of fourth-tier side Gillingham in 1995, helping them become a Football League side in his first season via promotion.
After his success with the Gills, Pulis had spells at Bristol City and Portsmouth before his first stint with Stoke City.
During this time he saved the club from relegation to the second division (now League One).
He went on to manage Plymouth for a season before returning to Stoke.
For the next seven years, Pulis turned the Potters into one of the hardest sides to beat in England and turned the Bet365 Stadium into a fortress.
He guided them to the Premier League and cemented them in as a mid-table side despite having a modest budget to work with.
Pulis also led Stoke to a FA Cup final and Europa League campaign while he was in charge.
He was eventually sacked in 2013 with the club in 13th place due to the club wanting to push on.
Pulis went on to Crystal Palace and won the manager of the year during the 2013/14 season after guiding the club to 11th in the Premier League.
But his time at Selhurst was cut short, leaving due to issues of his backing in the transfer market.
He would reach 1,000 games in management with his next club West Brom.
After leaving the Baggies, Pulis returned to the Championship and had a stint at Middlesborough, but was unable to take them past the play-offs in 2018.
He left the club in 2019 and joined his last club – Sheffield Wednesday – in 2020 but was dismissed due to disagreements with owner Dejphon Chansiri over transfers.
