Francesco Flarer (27 November 1791 – 22 December 1859) was an ophthalmologist born near Merano, South Tyrol, Holy Roman Empire.
He initially planned to study theology at Innsbruck, but instead enrolled to take classes in medicine, later relocating to the University of Landshut.
On advice from Antonio Scarpa (1752–1832), he studied ophthalmology in the clinic of Georg Joseph Beer (1763–1821) at the University of Vienna, where he obtained a degree in 1817.
Following his return to Pavia, he worked as an assistant in the anatomy laboratory of Bartolomeo Panizza (1785–1867).
Another noted work of his was a study of eyelid/eyelash maladies titled Riflessioni sulla Trichiasi, sulla Distichiasi e sull'Entropio, avuto particolare riguardo ai metodi di Jaeger e di Vaccà (Reflections on trichiasis, distichiasis and entropion, with particular regard to the methods of Friedrich Jäger von Jaxtthal (1784–1871) and Andrea Vaccá Berlinghieri (1772–1826).
