In golf, a double eagle is a scoring term that refers to a score of 3-under par on a hole, also known as an albatross. It is a rare achievement that happens when a golfer holes out from the fairway on the second shot on a par-5 hole or makes a hole-in-one on a par-4 hole. The term "double eagle" is used mainly in the United States, while "albatross" is used in other parts of the world. The origin of the term "double eagle" is unclear, and it does not make mathematical sense since it would imply a score of 4-under par. Double eagles are much rarer than holes-in-one because they almost always require holing out a stroke played from a fairway, as opposed to holing out a shot played off a tee on a par-3. In the entire history of The Masters Tournament, only four double eagles have been scored.
