"Misty Mourne Shore" is a traditional Irish love song. The air is also known by various other titles and lyrics, such as "The Maid of Mourne Shore", "Moorlough Mary", "Banks of the Moorlough Shore", "An Traigh Múghdhorna", "The Maids Of The Mountain Shore", "The Foggy Dew", "Down by the Salley Gardens", "Gort Na Saileán" and similar.

A young man praises the beauties of the countryside and the girl he has fallen in love with. She refuses his advances on the ground that she already loves a sailor. She will wait for her true love for seven years. In frustration the boy leaves his childhood home and sails away, still praising the girl he loves that lives by the Moorlough Shore. The song is set in Strabane, and local names and places along the River Mourne are mentioned.

The earliest version is a broadside in the Bodleian Library, dated 1886. The song is discussed in the "Journal of the Irish folk Song Society" in 1905 and 1911. In the 1940s Helen Hartness Flanders found a version in Vermont.
