The manchineel tree (Hippomane mancinella) is a species of flowering plant in the spurge family ( Euphorbiaceae). It is native to tropical southern North America and northern South America.

The name "manchineel" (sometimes written "manchioneel") as well as the specific epithet mancinella is from Spanish manzanilla ("little apple"), from the superficial resemblance of its fruit and leaves to those of an apple tree. A present-day Spanish name is in fact , "little apple of death". This refers to the fact that manchineel is one of the most dangerous trees in the world. Manchineel is also known as the beach apple.
