Alejandro Manuel Sinibaldi Castro (1825–1896) was acting President of Guatemala from April 2, 1885, to April 5, 1885.
Of partial Italian descent, Sinibaldi Castro was a businessman who was "First Designate to the Presidency", the equivalent of Vice-President, during the presidency of Justo Rufino Barrios.[citation needed]
When Barrios was killed on April 2, 1885, in El Salvador, Sinibaldi Castro became acting president.[1] However, given that Sinibaldi Castro had no political connections and was not in the military, he was pressured to resign within days of taking over.[1]
His successor was General Manuel Lisandro Barillas, who served as acting president, and was eventually elected as Constitutional President.[1]
