The Naul Hills, or Man-of-War Hills[2] are low-lying hills in north County Dublin, Ireland, close to the village of Naul, formerly called The Naul,[3] (Irish: An Aill, meaning 'the cliff'). They lie beside the County Meath border, 30 kilometres north of Dublin City (17 km north of the airport), 16 km north-northwest of Swords, and 8 km southwest of Balbriggan.[4]

Typical hill elevations run between 140 and 150 metres, with the highest point in the area being the 176m Knockbrack (Irish: An Cnoc Breac, meaning 'the speckled hill').[1][5] Limestone quarrying has been carried out in the hills, and the London Encyclopaedia (1829) remarked, "there are coals at Naul...but the coal vein is not worked."[6]
As a result of the COVID-19 pandemic, the temporary reduction in emissions as well as a period of sustained fine weather meant that Knockbrack was visible across the Irish Sea from Anglezarke, Lancashire for a period in May 2020.[7]
