Dalkey (/ˈdɔːki/ DAW-kee; Irish: Deilginis, meaning 'thorn island') is a village in Dún Laoghaire–Rathdown county southeast of Dublin, Ireland. It was founded as a Viking settlement and became a port in the Middle Ages. According to chronicler John Clyn (c.1286–c.1349), it was one of the ports through which the plague entered Ireland in the mid-14th century. The village is in a townland and civil parish of the same name, in the barony of Rathdown.
One of Dublin's wealthiest districts, it has been home to writers, artists, and celebrities, including George Bernard Shaw, Jane Emily Herbert, Julius Olsson, Maeve Binchy, Robert Fisk, and Hugh Leonard.
