William Reinhold Valentiner (May 2, 1880 – September 6, 1958) was a German-American art historian, art critic and museum administrator. He was educated and trained in Europe, first working at the Mauritshuis in The Hague and at museums in Berlin.

In 1907 he moved to the United States to become the first curator of the department of decorative arts in the Metropolitan Museum in New York City. After returning to Europe to serve in the German Army in World War I, Valentiner later was appointed to other positions in the US. From the mid-1920s, he strongly influenced the development of museum administration in the United States.
