Slamdjävul (Cryptobranchus alleganiensis) är ett stjärtgroddjur inom familjen jättesalamandrar och det tredje största stjärtgroddjuret i världen, efter kinesisk jättesalamander och japansk jättesalamander. Den lever (i motsats till sitt svenska namn) i klara, grunda strömmande vatten med stenig botten och god tillgång på syre. Till skillnad från de flesta andra salamandrar, men i likhet med till exempel grodor, har slamdjävulen yttre befruktning.
