Vivian Annabelle Johnson (1912–1985) was an American physicist, professor at Purdue University and researcher in theoretical solid state physics.
There, through her contacts, she was able to obtain a graduate assistantship at Purdue working for physicist Karl Lark-Horovitz who became her mentor.
Her early research contributed to the then-newly developing field of solid state physics.
During the years of World War II, some of her papers became classified information.
