Foil Allan Miller (January 18, 1916 – September 20, 2016) was an American chemist and philatelist best known for his work in infrared and Raman spectroscopy.

Among other publications, he co-authored the books Course Notes on the Interpretation of Infrared and Raman Spectra (2004) and A Philatelic Ramble Through Chemistry (1998).

[2][6] Miller was a pioneer in the areas of infrared and Raman spectroscopy, and their application to the understanding of molecular structure and bonding.

[2][6] An early paper with Charles H. Wilkins detailing the infrared spectra of common inorganic compounds was widely distributed by instrument manufacturers.

[7] With William G. Fateley, he wrote a number of papers on the determination of barriers to internal rotation, examining the far infrared.

[10] He was Secretary of the International Union of Pure and Applied Chemistry (IUPAC)'s Commission on Molecular Structure and Spectroscopy from 1969 to 1975.
