The list of Norwegian monarchs ( or kongerekka) begins in 872: the traditional dating of the Battle of Hafrsfjord, after which victorious King Harald Fairhair merged several petty kingdoms into that of his father. Named after the homonymous geographical region, Harald's realm was later to be known as the Kingdom of Norway. Traditionally established in 872 and existing continuously for over 1,100 years, the Kingdom of Norway is one of the oldest states of Europe: King Harald V, who has reigned since 1991, is the 64th monarch according to the official list. During interregna, Norway has been ruled by variously titled regents. Several royal dynasties have possessed the Throne of the Kingdom of Norway: the more prominent include the Fairhair dynasty (872–970), the House of Sverre (1184–1319), the House of Oldenburg (1450–1481, 1483–1533, 1537–1818, and from 1905),including branches Holstein-Gottorp (1814–1818) and Schleswig-Holstein-Sonderburg-Glücksburg (from 1905), and the House of Bernadotte (1818-1905). During the civil war era (1130–1240), several pretenders fought each other, and as a consequence, some rulers from this era are not traditionally considered lawful kings and are usually omitted from lists of monarchs. Between 1319 and 1905, Norway was part of various unions. Kings of Norway used many additional titles between 1450 and 1905, such as King of the Wends, King of the Goths, Duke of Schleswig, Duke of Holstein, Prince of Rügen, and Count of Oldenburg. They called themselves Konge til Norge ("King of Norway"), usually with the style His Royal Majesty. With the introduction of constitutional monarchy in 1814, the traditional style "by the Grace of God" was extended to "by the Grace of God and the Constitution of the Kingdom", but was only briefly in use. The last king to use the by the grace of God style was Haakon VII, who died in 1957. The King's title today is formally Norges Konge ("Norway's King"), with the style "His Majesty".

Fairhair dynasty

Besides becoming sole king after his father Harold's death, Eric Bloodaxe was king jointly with his father for three years before the latter's death. After Harald's death, Eric ruled as "overking" of his brothers, who also held status as kings and had control over certain regions. Harald Greycloak also ruled as "overking" of his brothers. All dates for the kings of the Fairhair dynasty are approximate and/or just scholarly estimates. Slight differences might therefore occur between different sources. The following table uses the dates given in Norsk biografisk leksikon/Store norske leksikon.

House of Gorm/Earl of Lade

The Danish king Harald Bluetooth had himself hailed as king of Norway after the Battle of Fitjar (c. 961). Besides gaining direct control of Viken in south-eastern Norway, he let Harald Greycloak rule the rest of Norway as king, nominally under himself. Harald Bluetooth later switched his support to Harald Greycloak's rival, Haakon Sigurdsson, Earl of Lade, who eventually captured Harald Greycloak's kingdom. Haakon thereafter ruled Norway (except Viken), at first nominally under Harald. All dates are estimates and subject to interpretation. Haakon is generally held as the ruler of Norway from 970 to 995.

Fairhair dynasty (restored)

House of Gorm/Earls of Lade (restored)

After the Battle of Svolder, the Danes recaptured Norway under Sweyn Forkbeard. As before, the Danes controlled the petty kingdoms of Viken as vassals, while the two Earls of Lade, Eric Haakonsson and Sweyn Haakonsson, ruled Western Norway and Trøndelag, nominally as earls under Sweyn. Eric is generally held as the de facto ruler of Norway from 1000 to 1015, together with his brother Sweyn, a lesser known figure, with whom he shared his power.
