Luigi Puccianti (Italian: [luˈiːdʒi putˈtʃanti]; 11 June 1875 – 9 June 1952) was an Italian physicist.


Puccianti is notable for having constructed a highly sensitive spectrograph, with which he studied the infrared absorption of many compounds and attempted to correlate the spectra with molecular structure. He studied the emission spectra of metals and halogens and proposed measuring the wavelength of X-rays by using a diffraction grating at large angles of incidence.

He is also particularly notable for being the academic advisor of the Nobel prize winner Enrico Fermi.
