The Vikings invaded the territory around Dublin in the 9th century, establishing the Norse Kingdom of Dublin, the earliest and longest-lasting Norse kingdom in the British Isles, excepting the Kingdom of Mann and the Isles. This corresponded to most of present-day County Dublin. The Norse referred to the kingdom as Dyflin, which is derived from Irish Dubh Linn, meaning "black pool". The first reference to the Vikings comes from the Annals of Ulster and the first entry for 841 AD reads: "Pagans still on Lough Neagh". It is from this date onwards that we get references to ship fortresses or longphorts being established in Ireland. It may be safe to assume that the Vikings first over-wintered in 840–841 AD. The actual location of the longphort of Dublin is still a hotly debated issue. Norse rulers of Dublin were often co-kings, and occasionally also Kings of Jórvík in what is now Yorkshire.

Over time, the rulers of Dublin became increasingly Gaelicized. They began to exhibit a great deal of Gaelic and Norse cultural syncretism, and are often referred to as Norse-Gaels.

The extent of the kingdom varied, but in peaceful times it extended roughly as far as Wicklow (Wykinglo) in the south, Glen Ding near Blessington, Leixlip (Lax Hlaup) west of Dublin, and Skerries, Dublin (Skere) to the north. The Fingal area north of Dublin was named after the Norse who lived there.

In 988, Máel Sechnaill mac Domnaill led the initial Irish conquest of Dublin. As a result the founding of Dublin is counted by some from the year 988, although a village had existed on the site of Dublin since before the Roman occupation of Great Britain nearly a thousand years earlier. Máel Sechnaill mac Domnaill was dethroned by Brian Boru (1002–1014).

In the mid 11th century, the Kingdom of Leinster began exerting influence over Dublin. Though the last king of Dublin was killed by the English conquerors of Dublin in 1171, the population of the city retained their distinctiveness for some further generations.

Donnchad mac Domnaill Remair 1086–1089 Member of the Uí Cheinnselaig; seized kingship following death of Toirdelbach Ua Briain; killed in 1089; control of Dublin appears to have been gained by Muirchertach Ua Briain not long afterwards.
Gofraid Crobán c. 1091–1094 Possibly a close relative of Ímar mac Arailt and thus a member of the Uí Ímair; founder of the Crovan dynasty; ruler of the Isles; seized kingship in about 1091 and expulsed by Muirchertach in 1094.

Magnús berfœttr 1102–1103 Ruler of Norway; appears to have seized Dublin in the early twelfth century, having taken Orkney and the Isles before the turn of the century; seems to have intended for his son, Sigurðr, to rule as king of these newly-won overseas Norse territories.

Ragnall mac Torcaill 1144×1146 Member of the Meic Torcaill; styled king on his death in 1146, which could be evidence that his reign interrupted that of Ottar; another possibility is that he was merely a subordinate of Ottar.
