Ebbsfleet United forward McLean, 34, will now focus on a career in coaching after confirming he is to hang up his boots.
Part of Daryl McMahon’s backroom team, who played for 11 clubs in his 17-year career, is a popular figure within the game.
McLean went on to play in the Premier League for Hull City after scoring 67 goals for Peterborough United.
He earned a move to London Road after his great record in Non-League football, with Grays Athletic and Aldershot Town.
He also turned out for Barnet, Bradford City, Leyton Orient, Ipswich Town and Birmingham City.
“I would like to thank everybody who has helped and supported me throughout my career,” said the forward.
“I have worked with some brilliant managers and coaches, played in some amazing stadiums with amazing players.
“Retirement comes to us all and I am grateful that I am able to pass on the knowledge I’ve gained from 19 years in the game.”
