Etymology  Crocodylus: 'crocodile'.
johnstoni: after Mr Johnston, the first European to report it to science. Krefft repeatedly mis-spelled the species name as "johnsoni" in his initial description, but later corrected it. According to the rules of the International Commission on Zoological Nomenclature the original, unintentional name is the correct name, but most people and publications use "johnstoni" as Krefft had intended.
