Susan Margaret Love (February 9, 1948 – July 2, 2023) was an American surgeon, a prominent advocate of preventive breast cancer research, and author.

In 1993, she and her partner Dr. Helen Cooksey made history by getting approval for the first joint adoption by a gay couple from the Massachusetts Supreme Judicial Court, a state that did not recognize same-sex marriage at the time.

[8] After a successful treatment, Love returned to work the following year,[9] but died from a recurrence of the disease on July 2, 2023, at the age of 75, at her home in Los Angeles.

After leaving the Faulkner Hospital in Boston, Love was recruited to set up what later became the Revlon Breast Center at University of California, Los Angeles (UCLA) in 1992.

According to The New York Times, Love sought "not so much to cure the disease as to vanquish it altogether by isolating its causes and pre-empting them at a cellular level".
