The Puerto Rican Campaign (also: San Juan Campaign) refers to American operations on the island of Puerto Rico in the final stages of the Spanish-American War.

Left unfinished by the announcement of the armistice on August 13, the conquest of Puerto Rico was generally regarded as an easy American victory by the press and neutral observers, although Spanish opposition along the island's fortified northwest had stiffened considerably and may indeed have proven fierce had the campaign gone on.
