Arturo Belleza Rotor (June 7, 1907 – April 9, 1988) was a Filipino medical doctor, civil servant, musician, and writer.

He trained further at Johns Hopkins University's medical school, publishing a paper on a rare form of hyperbilirubinaemia (jaundice) now known as "Rotor syndrome".

In the immediate post-World War II period, he was appointed secretary of the Department of Health and Welfare.

Later, Rotor was director of the University of the Philippines' Postgraduate School of Medicine and was a practising physician until the early 1980s.

Rotor died in 1988 from cancer and was survived by his wife Emma Unson, who taught college mathematics and physics.
