The Battle of Weihaiwei was a battle of the First Sino-Japanese War. It took place between 20 January and 12 February 1895, in Weihai, Shandong Province, China, between the forces of Japan and Qing China. In early January 1895, the Japanese landed forces in eastern Shandong positioning forces behind the Chinese naval base at Weihaiwei.

Through a well-coordinated offensive of both naval and land forces, the Japanese destroyed the forts and sank much of the Chinese fleet. With the Shandong and Liaoning peninsulas under Japanese control, the option for a pincer attack against the Chinese capital, Beijing, was now a possibility. This strategic threat forced the Chinese to sue for peace and led to the war's end in April 1895.
