Pol F. Swings (24 September 1906 – 28 October 1983) was a Belgian astrophysicist who was known for his studies of the composition and structure of stars and comets.

Swings studied at the University of Liège, where he was professor of spectroscopy and astrophysics from 1932 to 1975.

Swings bands are emission lines resulting from the presence of certain atoms of carbon; the Swings effect was discovered with the aid of a slit spectrograph and is attributed to fluorescence resulting partly from solar radiation.

Pol Swings was awarded the Francqui Prize for Exact Sciences in 1948.

[2][3] In 1981, Swings became a founding member of the World Cultural Council.
