Under the Frog is the 1992 debut novel of British writer Tibor Fischer.

[1] The book was a winner of the 1992 Betty Trask Award[2] and was the first debut novel to be shortlisted for the Booker Prize.

[1][3] The novel is a black comedy set in Hungary in the years immediately following the end of World War II and culminates in the 1956 uprising.

The book especially parodies the trumpeting of the "gains of socialism" by the regime, empty rhetoric which, Fischer suggests, all but the dimmest were able to see through even from the beginning.

The title is taken from a Hungarian expression, "a béka segge alatt" used to describe any situation when things can't seem to get any worse: "under a frog's arse, down a coalmine".
