The Scarlet Professor is an opera by the American composer Eric Sawyer with libretto by Harley Erdman, based on the biography^[1] by Barry Werth.

The world premieres of the fully staged opera occurred on September 15–17, 2017, at Smith College where the events that inspired the performance took place. The opera was performed without intermission with running time of about one hour and 40 minutes. A symposium^[2] on the Arvin case was held all day on September 16. The following weekend the opera was performed with a cast of young artists from the Five Colleges consortium of Western Massachusetts.

The 9-piece instrumental ensemble consisted of piano, percussion, flute, clarinet, tenor saxophone, and strings, with both electric and double bass.

Reviewer Marvin J. Ward found the opera a "compelling and captivating work", adding "...composer Eric Sawyer has a penchant for choosing historical events, especially local ones, as the subjects of his operas. This is the third that I have seen, each more polished and refined than its predecessor, with The Scarlet Professor scoring a 10/10 in my book."^[3] The Scarlet Professor won the 2019 American Prize in opera composition.^[4]
