John Britton, American physician (b. 1925)
John Bayard Britton (May 6, 1925 – July 29, 1994) was an American physician. He was murdered in Pensacola, Florida, by anti-abortion extremist Paul Jennings Hill. Britton's death was the second assassination of a Pensacola abortion provider in under a year and a half; he had replaced David Gunn after the latter's 1993 murder by another anti-abortionist.

Born in Boston, Britton graduated in 1949 from the University of Virginia School of Medicine, then served in the US Army stationed in Korea and also taught at the Medical College of Georgia. He then became a family physician in Fernandina Beach, Florida, spending much of his time delivering babies.After Gunn's murder, Britton began flying across the state to Pensacola weekly in order to perform abortions at the Pensacola Ladies' Center. Because he had received harassment and death threats, he wore a homemade bulletproof vest, carried a .357 Magnum, and enlisted volunteer bodyguards.Britton was notably ambivalent about abortion: he viewed abortion as a last resort option, and would sometimes turn away women seeking it, telling them to think about the decision and come back in a week if they still wanted an abortion. However, he described anti-abortion protesters as "fanatics."
