A winged unicorn is a fictional equine with the wings of a winged horse and the horn of a unicorn. There is no specific name given to such creature, but it is sometimes referred to using a portmanteau of pegasus and unicorn.
Irish poet W. B. Yeats wrote of imagining a winged beast that he associated with laughing, ecstatic destruction. The beast took the form of a winged unicorn in his 1907 play The Unicorn from the Stars and later that of the rough beast slouching towards Bethlehem in his poem The Second Coming.
In the continuity of Hasbro's My Little Pony and its related media after 2010 (including its My Little Pony: Friendship Is Magic television series), winged unicorns[nb 1] play a role as ponies of royal status. Two of them, Celestia and Luna, who are sisters, are also the rulers of Equestria, a major fictional setting in the continuity. 
- In the early episodes of the My Little Pony: Friendship Is Magic television series, the species is not specifically named; for example, the sisters Celestia and Luna were referred as unicorns in first season's première episode "Friendship Is Magic - part 1" despite having wings. However, an amulet with a pair of wings and a horned head of a horse is referred as the "Alicorn Amulet" in the third season's fifth episode "Magic Duel" (written by M. A. Larson), and the species is explicitly named "alicorn" in its season finale "Magical Mystery Cure" (also written by Larson).
