"Danny Boy" is a ballad, written by English songwriter Frederic Weatherly in 1913, and set to the traditional Irish melody of "Londonderry Air". In 1910, in Bath, Somerset, the English lawyer and lyricist Frederic Weatherly initially wrote the words to "Danny Boy" to a tune other than "Londonderry Air". After his Irish-born sister-in-law Margaret Enright Weatherly (known as Jess) in the United States sent him a copy of "Londonderry Air" in 1913 (an alternative version of the story has her singing the air to him in 1912 with different lyrics), Weatherly modified the lyrics of "Danny Boy" to fit the rhyme and meter of "Londonderry Air". Weatherly gave the song to the vocalist Elsie Griffin, who made it one of the most popular songs in the new century. In 1915, Ernestine Schumann-Heink produced the first recording of "Danny Boy". Jane Ross of Limavady is credited with collecting the melody of "Londonderry Air" in the mid-19th century from a musician she encountered.

Various suggestions exist as to the true meaning of "Danny Boy". Some have interpreted the song to be a message from a parent to a son going off to a war or uprising (as suggested by the reference to "pipes calling glen to glen") or leaving as part of the Irish diaspora.

The 1918 version of the sheet music with Weatherly's printed signature included alternative lyrics ("Eily Dear"), with the instructions that "when sung by a man, the words in italic should be used; the song then becomes "Eily Dear", so that "Danny Boy" is only to be sung by a lady". In spite of this, it is unclear whether this was Weatherly's intent. The song has been performed by a diverse range of male singers, including Irish tenor John McCormack, Jim Reeves, Mario Lanza, Bing Crosby, Andy Williams, Eric Clapton, Johnny Cash, Sam Cooke, Elvis Presley, Shane MacGowan, Jackie Wilson, Daniel O'Donnell, Harry Belafonte, Tom Jones, John Gary, Frank Patterson, Thomas Quasthoff, Stuart Burrows, Jacob Collier, Harry Connick Jr., and comedian Peter Kay amongst many others. All used the original lyrics with slight variations.
