"Yes, Virginia, there is a Santa Claus" is a line from an editorial by Francis Pharcellus Church titled "Is There a Santa Claus?", which appeared in the New York newspaper The Sun on September 21, 1897, and became one of the most famous editorials ever published. Written in response to a letter by eight-year-old Virginia O'Hanlon asking whether Santa Claus was real, the editorial was initially published anonymously and Church's authorship was not disclosed until after his 1906 death. As the editorial became popular over the years, The Sun began republishing it during the Christmas season, including every year from 1924 to 1950, when the paper ceased publication.

"Is There a Santa Claus?" is widely reprinted during the Christmas and holiday season and has been cited as the most reprinted newspaper editorial in the English language. It has been translated into around 20 languages and adapted as a film, television presentations, a musical, and a cantata.
