James Justinian Morier (15 August 1782 – 19 March 1849)[a] was a British diplomat and author noted for his novels about the Qajar dynasty in Iran, most famously for the Hajji Baba series.

[citation needed] After his return to England he published A second journey through Persia, Armenia, and Asia Minor, to Constantinople, between the years 1810 and 1816.

There followed Zohrab the Hostage (1832), Ayesha the Maid of Kars (1834), and The Mirza (1841), all full of brilliant description, character-painting, and delicate satire, and several others of lesser quality.

Some later editions have been prefaced by Walter Scott's generous appreciation of Morier's work, first published in the Quarterly Review in January 1829.

published Moriera a genus of flowering plants from Central Asia, belonging to the family Brassicaceae in his honour.
