Stephen Porter Dunn (March 24, 1928 – June 4, 1999, Kensington, California) was a U.S. anthropologist specializing in ethnic groups of the Soviet Union.
He translated and edited a number of works on the topic from the Russian language, and lectured in several universities.
His parents provided him with the opportunity to travel in Norway, Sweden, France, England, Ireland, and Italy as a boy and young man.
In spite of a widely held opinion that due to his disease, Dunn could not teach, he did teach courses in the peoples of the USSR (at Monterey Institute of Foreign Studies, 1970–74, at the University of California, Berkeley, 1980, and San Francisco State University) and comparative religion.
At the time of his death, Dunn was survived by his wife, two nieces, a nephew, two great-nieces and a great-nephew.
