Jonah Placid (born 14 May 1995) is an Australian rugby union player who currently plays as a fullback for the Reds in Super Rugby. Domestically, he plays for Easts in the Queensland Premier Rugby tournament.
Born in New South Wales, but raised in Rockhampton, Queensland, Placid first came to prominence playing for Easts Tigers and he helped them win the 2013 Queensland Premier Rugby Title. This saw him named in the Queensland Reds wider training squad for the 2014 Super Rugby season. Although this was largely a development contract and he seemed unlikely to be given any game time during the campaign, an injury crisis saw him make his Super Rugby debut as a second half replacement against the Western Force on 5 April 2014. It was to prove an unhappy debut as his side went down to 32-29 defeat and he himself had to be substituted with a chest injury following a heavy collision with Force fullback Jayden Hayward.
