Pi Upsilon Rho (ΠΥΡ) was a United States-based professional fraternity for homeopathy students established at Hahnemann Medical College in 1876 under the name Ustion. It changed its name to Pi Upsilon Rho in 1909.

By 1920 it had five active chapters. It has been credited as one of the United States' oldest medical fraternities. The fraternity's governing body, the Supreme Corpus, would meet annually at the convention of the American Institute of Homeopathy.
