Fingal mac Gofraid, and his father Gofraid mac Sitriuc (d. 1070), are late 11th century rulers of the Kingdom of the Isles.
The men are likely members of the Uí Ímair, and possibly descendants of Amlaíb Cuarán, King of Dublin and Northumbria (d. 980).
In the first half of the 11th century, Amlaíb Cuarán's son, Sitric mac Amlaíb, King of Dublin, is driven from the kingship of Dublin by Echmarcach mac Ragnaill, a man who seems to have represented a rival branch of the Uí Ímair.
Echmarcach appears to have eventually ruled a realm which spans from Dublin to the Galloway, and from the Isle of Man (Mann) into the Hebrides.
By the mid 11th century, Echmarcach's once expansive realm has eroded to successive conquests by Diarmait mac Máel na mBó, King of Leinster.
After Echmarcach's expulsion from Mann, in 1061, Diarmait appears to have placed Gofraid on the island, as King of the Isles.
Gofraid rules on Mann until his death, in 1070.
His son, Fingal, succeeds to the kingship, and rules for almost a decade.
During his reign, Fingal fends off an attack upon Mann by men with Irish connections.
In the later 1070s, Mann is conquered by Gofraid Crobán, a likely Uí Ímair kinsman, who had been welcomed to the island by Fingal's father about a decade before.
It is unknown whether Fingal was overthrown by Gofraid Crobán, or if he had died beforehand.
An obituary dated about a decade later, for a certain King of the Rhinns, may indicate that descendants of Fingal ruled territory in Galloway after the conquest.
It is unknown whether or not this man ruled subordinately to Gofraid Crobán.
