The German attacks on Nauru refers to the two attacks on Nauru in December 1940. Nauru is an island country in Micronesia, a subregion of Oceania, in the Central Pacific. These attacks were conducted by auxiliary cruisers between 6 and 8 December and on 27 December. The raiders sank five Allied merchant ships and inflicted serious damage on Nauru's economically important phosphate-loading facilities. Despite the significance of the island to the Australian and New Zealand economies, Nauru was not defended and the German force did not suffer any losses.

The two attacks were the most effective operations conducted by German raiders in the Pacific Ocean in World War II. They disrupted supplies of phosphate to Australia, New Zealand and Japan, which reduced agricultural production in these countries. In response, Allied naval vessels were deployed to protect Nauru and nearby Ocean Island and escort shipping in the South Pacific. Small garrisons were also established to protect the two islands.
