The Rubalcaba Incident (also known as the Rubalcaba Expedition) was a diplomatic conflict and a naval demonstration of force carried out by the Spanish Navy against the Republic of Haiti in July 1861.

In March 1861, Dominican General Pedro Santana proclaimed the reincorporation of the Dominican Republic into the Spanish Crown.
