Elizabeth Ness MacBean Ross (14 February 1878 – 14 February 1915) was a Scottish physician who worked in Persia (presently Iran) among the Bakhtiari people. With training and a post-graduate qualification in tropical medicine, she responded to an appeal for doctors by the Serbian government in 1915 and treated Serbian casualties, most of whom were victims of typhus. Ross's life and work is commemorated by a plaque in her home town of Tain and her death anniversary is commemorated by ceremonies in Serbia, on 14 February.
