"Tie a Yellow Ribbon Round the Ole Oak Tree" is a song recorded by Tony Orlando and Dawn. It was written by Irwin Levine and L. Russell Brown and produced by Hank Medress and Dave Appell, with Motown/Stax backing vocalist Telma Hopkins, Joyce Vincent Wilson and her sister Pamela Vincent on backing vocals. It was a worldwide hit for the group in 1973.

The single reached the top 10 in ten countries, in eight of which it topped the charts. It reached number one on both the US and UK charts for four weeks in April 1973, number one on the Australian charts for seven weeks from May to July 1973 and number one on the New Zealand charts for ten weeks from June to August 1973. It was the top-selling single in 1973 in both the US and UK.

In 2008, Billboard ranked the song as the 37th biggest song of all time in its issue celebrating the 50th anniversary of the Hot 100. For the 60th anniversary in 2018, the song still ranked in the top 50, at number 46

The song is told from the point of view of someone who has "done his time" but is uncertain if he will be welcomed home.

He writes to his love, asking her to tie a yellow ribbon around the "ole oak tree" in front of the house (which the bus will pass by) if she wants him to return to her life; if he does not see such a ribbon, he will remain on the bus (taking that to mean he is unwelcome) and understand her reasons ("put the blame on me"). He asks the bus driver to check, fearful of not seeing anything.

To his amazement, the entire bus cheers the response – there are 100 yellow ribbons around the tree, a sign he is very much welcome.

The origin of the idea of a yellow ribbon as remembrance may have been the 19th-century practice that some women allegedly had of wearing a yellow ribbon in their hair to signify their devotion to a husband or sweetheart serving in the U.S. Cavalry. The song "'Round Her Neck She Wears a Yeller Ribbon", tracing back centuries but copyrighted by George A. Norton in 1917, and later inspiring the John Wayne movie She Wore a Yellow Ribbon, is a reference to this. The symbol of a yellow ribbon became widely known in civilian life in the 1970s as a reminder that an absent loved one, either in the military or in jail, would be welcomed home on their return.

In October 1971, newspaper columnist Pete Hamill wrote a piece for the New York Post called "Going Home". In it, he told a variant of the story, in which college students on a bus trip to the beaches of Fort Lauderdale make friends with an ex-convict who is watching for a yellow handkerchief on a roadside oak in Brunswick, Georgia. Hamill claimed to have heard this story in oral tradition. In June 1972, nine months later, Reader's Digest reprinted "Going Home". Also in June 1972, ABC-TV aired a dramatized version of it in which James Earl Jones played the role of the returning ex-con. According to L. Russell Brown, he read Hamill's story in the Reader's Digest, and suggested to his songwriting partner Irwin Levine that they write a song based on it. Levine and Brown then registered for copyright the song which they called "Tie a Yellow Ribbon 'Round the Ole Oak Tree". At the time, the writers said they heard the story while serving in the military. Pete Hamill was not convinced and filed suit for infringement. Hamill dropped his suit after folklorists working for Levine and Brown turned up archival versions of the story that had been collected before "Going Home" had been written.

Levine and Brown first offered the song to Ringo Starr, but Al Steckler of Apple Records told them that they should be ashamed of the song and described it as "ridiculous"
