Johann Georg August Galletti (19 August 1750 – 16 March 1828) was a German historian and geographer.

Galletti was born in Altenburg. His fame is not based on his merits as an academic, but on his reputation as the creator of a few hundreds of stylistic howlers, becoming a legend as Kathederblüten (teacher's howlers) originated during his time as a professor at the Ernestine Gymnasium in Gotha. He was known as the "absent-minded professor of Gotha" and died there aged 77.

Some Kathederblüten of Galletti:

• After the Battle of Leipzig you could see horses with three, four, or even more legs shot off running loose all over the countryside.
• Deiotarus was his father's son.
• Indeed, Councillor, I am well pleased with Blädner, but with Seifert not at all; but at least he's better than Blädner.
• So you think that history is as easy as playing schnapsen? Ha! You can learn history in a flash, but learning schnapsen takes years of hard graft.

• Charlemagne won as often against the Saxons that in the end they wouldn't even wait for it any-more.
• Among the masterpieces of Demosthenes, we have his celebrated speech on the wreath. This speech is well known to begin with the immortal words: "Which rascal is throwing spit wads here again?"
• And you, Schäfer, you don't belong amongst decent people at all. Come to me at the lectern in front.
• The Persians cried out loud: "Good Lord Jesus, the Athenians are coming!" and threw themselves into the sea.
