Arbour Hill (Irish: Cnoc an Arbhair[1]) is an area of Dublin within the inner city on the Northside of the River Liffey, in the Dublin 7 postal district.

Arbour Hill, the road of the same name, runs west from Blackhall Place in Stoneybatter, and separates Collins Barracks, now hosting part of the National Museum of Ireland, to the south from Arbour Hill Prison to the north,[2] whose graveyard includes the burial plot of the signatories of the Easter Proclamation and other leaders executed after the 1916 Rising.

The area was owned by Christ Church Cathedral during the medieval period and was used to store corn.

[3] As part of his commissioned symphonic work "Irishmen and Irishwomen", the composer Vincent Kennedy included a movement titled "Arbour Hill".

[4] This movement is a tribute to the Easter Rising participants buried at Arbour Hill.
