Manuel José Blanco y Calvo de Encalada (Latin American Spanish: [maˈnwel ˈβlaŋko eŋkaˈlaða]; April 21, 1790 – September 5, 1876) was a vice-admiral in the Chilean Navy, a political figure, and Chile's first President (Provisional) (1826).

Born in Buenos Aires which was the capital of the Viceroyalty of the Río de la Plata, Blanco Encalada was the son of the Spanish Manuel Lorenzo Blanco Cicerón and of the Chilean Mercedes Calvo de Encalada y Recabarren.

The following year, Congress elected him to the newly established position of President of the Republic.

He soon had several fights with Congress, which was trying to install a federalist system, and resigned within two months.
