Platytropius siamensis was a species of schilbid catfish (order Siluriformes) family Schilbeidae. It originated from the Chao Phraya and Bang Pakong Rivers in Thailand. It inhabited lower to middle reaches, mainstreams, tributaries, and larger marshlands. The species has been declared extinct in 2011 by the IUCN Red List of Threatened Species, because despite periodic surveys it has not been encountered since 1975–1977.
