Mammea americana, commonly known as mammee, mammee apple, mamey, mamey apple, Santo Domingo apricot, tropical apricot, or South American apricot, is an evergreen tree of the family Calophyllaceae, whose fruit is edible. It has also been classified as belonging to the family Guttiferae Juss. (1789), which would make it a relative of the mangosteen

In certain Latin American countries Mammea americana is referred to as "yellow mamey" (Spanish: Mamey amarillo) in order to distinguish it from the unrelated but similar looking Pouteria sapota, whose fruit is usually called "red mamey" (Spanish: Mamey colorado or Mamey rojo).
