Arne Zettersten (1934-) is a Swedish professor emeritus in English at the University of Copenhagen.
In 1965, Zettersten presented his doctoral thesis on the AB language, a medieval literary dialect first identified by J.R.R. Tolkien. And during the 1960s in Oxford, Zettersten became a friend and colleague of Tolkien, as they both shared an interest in a certain collection of medieval manuscripts (the "Katherine Group"). Their contact continued throughout the last 13 years of Tolkien's life.
