Vikings invaded the territory around Dublin in the 9th century, establishing the Norse Kingdom of Dublin, the earliest and longest-lasting Norse kingdom in Ireland. Its territory corresponded to most of present-day County Dublin. The Norse referred to the kingdom as Dyflin, which is derived from Dubh Linn '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 onward that historians 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. Under their rule, Dublin became the biggest slave port in Western Europe. The hinterland of Dublin in the Norse period was named in Old Norse: Dyflinnar skíði, lit. 'Dublinshire'.

Over time, the settlers in 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 Gaelic 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 nearly a thousand years earlier.

Coins were minted in Dublin by about 995, and on Mann by about 1025.

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

Gofraid mac Amlaíb meic Ragnaill	1072–1075	Member of the Meic Ragnaill (Uí Ímair); ruled under the overlordship of Toirdelbach; expelled from kingship by Toirdelbach in 1075; possibly identical to Gofraid mac Sitriuc, King of the Isles (died 1070).
Domnall mac Murchada	1075	Member of the Meic Murchada (Uí Chennselaig); gained kingship following the expulsion of Gofraid mac Amlaíb meic Ragnaill; may have seized Dublin without the consent of the Uí Briain, or else ruled under their overlordship; died within the year.

Donnchad mac Domnaill Remair	1086–1089	Member of the Uí Cheinnselaig; seized kingship following death of Toirdelbach; killed in 1089; control of Dublin appears to have been gained by Muirchertach 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.
Domnall mac Taidc		Member of the Meic Taidc (Uí Briain); possibly installed king by his uncle, Muirchertach, after Gofraid Crobán's expulsion; certainly installed as ruler of the Isles at about this time.
Domnall Gerrlámhach		Member of the Uí Briain; possibly installed king by his father, Muirchertach, after Gofraid Crobán's expulsion; certainly held kingship at a later date.
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.
Domnall Gerrlámhach		Defended Dublin from Leinster attack in 1115; possibly installed king by his father long before battle, immediately before, or immediately afterwards.
Diarmait mac Énna meic Murchada	×1117.	Member of the Meic Murchada (Uí Chennselaig); died 1117.
Domnall Gerrlámhach	1117–1118	Seized kingship after Diarmait 's death.
Toirdelbach Ua Conchobair	×1118	Member of the Uí Conchobair; drove Domnall Gerrlámhach from kingship.
Énna Mac Murchada	×1122–1126	Member of the Meic Murchada (Uí Chennselaig); either seized kingship or was installed king by Toirdelbach; reigned under Uí Conchobair overlordship.

Ottar mac meic Ottair	1142–1148	Member of the Meic Ottair; gained kingship in 1142; slain by the Meic Torcaill in 1148; may not have reigned continuously from 1142 to 1148.
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.
Brodar mac Torcaill	×1160	Member of the Meic Torcaill; killed in 1160.
Gofraid mac Amlaíb	1150s or 1160s	Member of the Crovan dynasty; ruler of the Isles; held kingship of Dublin briefly at the behest of the Dubliners, although the chronology of his short reign is uncertain.
