Dendrobates is a genus of poison dart frogs native to Central and South America.

It once contained numerous species, but most originally placed in this genus have been split off into other genera such as Adelphobates, Ameerega, Andinobates, Epipedobates, Excidobates, Oophaga, Phyllobates and Ranitomeya (essentially all the brightly marked poison dart frogs; i.e. excluding the duller genera in the family like Colostethus and Hyloxalus), leaving only five large to medium-sized species in the genus Dendrobates.

[1][2] All the other genera used to be grouped in with Dendrobates because it was previously thought that all brightly colored poison dart frogs came from the same ancestor but this has since been proven to be incorrect.

[3] Dendrobates and Phyllobates evolved conspicuous coloration from the same common ancestor but not the same as any of the other genera listed above.

[5] The generic name Dendrobates is derived from Ancient Greek δένδρον déndron 'tree' and βάτης bátēs 'one that treads', meaning ‘tree climber’.
