Der Giftpilz (German for "The Poisonous Mushroom" or "The Poisonous Toadstool") is a piece of antisemitic Nazi propaganda published as a children's book by Julius Streicher in 1938.

[1] The text is by Ernst Hiemer, with illustrations by Philipp Rupprecht (also known as Fips); the title alludes to how, just as it is difficult to tell a poisonous mushroom from an edible mushroom, it is difficult to tell a Jew apart from a Gentile.

After the war, Streicher was convicted of being an accessory for crimes against humanity in the Nuremberg trials and executed in 1946.

The Estonian Internal Security Service has investigated the case under the section of Estonian penal code criminalizing incitement to social hatred, but concluded that it is unlikely to have the jurisdiction or means to prosecute the author, as under American law, websites are covered by the First Amendment to the United States Constitution.
