John Patrick Platten (born 17 March 1963) is a retired Australian Rules Football player.
Platten remains a popular and respected figure at both clubs and is also an inductee in both the AFL and SANFL Halls of Fame.
Nicknamed "The Rat" because of his diminutive frame and unruly tangle of curly hair, he was a distinctive if unlikely-looking footballer.
In 1998, Platten retired from the Hawthorn Football Club and made a dramatic return to Central District along with Gilbert McAdam, another of the Bulldogs' all-time greats.
Platten was a notable attendee at Centrals early 2000s premiership successes, an achievement he was never to enjoy with his boyhood club.
