Mirza Fattah Khan Garmrudi (Persian: میرزا فتاح خان گرم‌رودی; c. 1786 – 1848) was a scribe and author in Qajar Iran, mainly known for his travelogue about his diplomatic missions to Europe, entitled Chaharfasl.

In 1834, when Mohammad Shah Qajar ascended the throne, Garmrudi was called to Tehran and made lashkar-nevis (chief clerk) of the army.

Garmrudi was included in this mission, likely due to the support of Mirza Masud Khan Ansari, who served as the minister of foreign affairs during this period.

[1] Garmrudi's Shabnama, a defamatory tale accusing the British of sexual depravity and debauchery, was another work created due to his travels throughout Europe.

The book was possibly meant as a counter to The Adventures of Hajji Baba of Ispahan by James Justinian Morier, which portrayed a negative image of Iranians.
