Wilhelm Müller-Wismar was a German ethnographer (May 20, 1881 – October 13, 1916) who was a native of Wismar.
In 1905 he graduated from the University of Berlin, where he studied ethnography and anthropology under Felix von Luschan (1854-1924).
From 1908 to 1910 he was a member of a scientific mission to the South Pacific that was coordinated by Georg Thilenius (1868-1937) of the Hamburg Museum of Ethnography. On the expedition he spent nine months on the island of Yap, about which an important scientific treatise was later published. He also took part in the Berlin-Indonesian expedition to the South Moluccas in 1913-14. Müller-Wismar died from typhoid on October 10, 1916 at the age of 35 in Malang, Java.
