The 1895 Wilcox rebellion, or the Counter-Revolution of 1895 was a brief war from January 6 to January 9, 1895, that consisted of three battles on the island of Oʻahu, Republic of Hawaii. It was the last major military operation by royalists who opposed the overthrow of the Kingdom of Hawaii.

The Republic of Hawaii was a short-lived one-party state in Hawaiʻi between July 4, 1894, when the Provisional Government of Hawaii had ended, and August 12, 1898, when it became annexed by the United States as an unincorporated and unorganized territory. In 1893, the Committee of Public Safety overthrew Queen Liliʻuokalani, the monarch of the Kingdom of Hawaiʻi, after she rejected the 1887 Bayonet Constitution. The Committee of Public Safety intended for Hawaii to be annexed by the United States; however, President Grover Cleveland, a Democrat opposed to imperialism, refused. A new constitution was subsequently written while Hawaii was being prepared for annexation.
