"Nancy Mulligan" is a song by English singer-songwriter Ed Sheeran. It was included on the deluxe edition of his third studio album ÷ (2017). After the album's release it charted at number 13 on the UK Singles Chart, despite not being an official single. Sheeran recorded the song together with Beoga.

"Nancy Mulligan" is one of the most personal songs on the album, telling the story of how his grandparents, William Sheeran, a Protestant from Maghera, County Londonderry, Northern Ireland and Anne Mulligan, a Catholic from County Wexford, Republic of Ireland, met and fell in love during the Second World War.

In an interview with the Irish Times, talking about the song's Irish roots, Sheeran said "I don't think enough people use [Irish pop] in pop music... Hopefully if these songs are successful, more people will do a bit more like it."

In 2017, the song was covered by the Irish country singer Mike Denver with an accompanying music video.

Sheeran performed the song, backed on stage by Beoga, during his headline performance at the Glastonbury Festival.
