No, durian and soursop are two different fruits. Durian is a large tropical fruit that grows on trees in Southeast Asia, while soursop is a smaller green fruit native to Central and South America.  They have very similar flavors but come from different parts of the world.  Durian has a strong smell that many people either love or hate, while soursop has a pineapple-like aroma with hints of sweetness. Both fruits are popular in desserts due to their sweet and creamy texture; however, soursop is more often used for its medicinal properties as it contains high amounts of vitamins, minerals, and antioxidants.
