Fear of frogs and toads is both a known specific phobia, known simply as frog phobia or ranidaphobia (from "ranidae", the most widespread family of frogs), and a superstition common to the folkways of many cultures. Psychiatric speciality literature uses the simple term "fear of frogs" rather than any specialized term. The term batrachophobia has also been recorded in a 1953 psychiatric dictionary.

According to some, the sight of a frog may be a bad omen. As well, a common myth says that touching frogs and toads may give one warts. (In many other cultures, frogs are considered a good omen.) A survey carried out by researchers from the Johannesburg Zoo have shown that in modern times old superstitions play a less significant role and modern children are more concerned whether frogs are poisonous or harmless.
