Alfred Nailer Jacobs MM (11 July 1897 – 26 January 1976) was an Australian medical practitioner and campaigner for civil liberties and Aboriginal rights.
He attended Scotch College and the University of Melbourne but suspended his education during World War I to enlist in the Australian Imperial Force (5 January 1916), serving on the Western Front in the 15th Field Ambulance.
He won the Military Medal for his actions on 29–30 September 1918 at Bellicourt, where he evacuated the wounded under heavy fire for thirty-six hours continuously.
He ran unsuccessfully for the Senate in 1934 (for Social Credit) and for the Western Australian Legislative Council in 1944 (for Labor) and 1968 (as an independent).
He was one of the founders of the Narrogin Native Welfare Committee in 1946, which campaigned for full citizenship rights and better opportunities for indigenous people.
