Islandmagee (from Irish Oileán Mhic Aodha, meaning 'Magee’s island/peninsula')[1] is a peninsula and civil parish on the east coast of County Antrim, Northern Ireland, located between the towns of Larne and Whitehead.

It is part of the Mid and East Antrim Borough Council area and is a sparsely populated rural community with a long history since the mesolithic period.

[1] The Bissett family held the tenancy of the peninsula in Elizabeth I's reign (1558 - 1603), their rent being an annual offering of goshawks, birds which bred on the rugged white chalk cliffs nearby.

In November 1641, roughly a month after the outbreak of the Irish Rebellion of 1641, several Catholic civilians living in Islandmagee were killed by troops from the nearby garrison at Carrickfergus.

Despite claims by an anonymous 17th-century author that the dead amounted to "above 3,000 men women and children",[2] the true figure is now thought to have been two dozen.
