Since the early 20th century, both the bay and the city have had several different names, often with varying English spellings.

In World War II Teluk Yos Sudarso was known as Humboldt Bay, and Jayapura was known as Hollandia. Occupied by the Japanese in April 1942, the area was liberated by U.S. forces on April 22, 1944, and became home to a massive U.S. naval base. It served as General Douglas MacArthur's headquarters until the conquest of the Philippines in March 1945.
