Howth Head (/ˈhoʊθ/ HOHTH; Ceann Bhinn Éadair in Irish) is a peninsula northeast of the city of Dublin in Ireland, within the governance of Fingal County Council.

The earliest mention of the peninsula may be on a map attributed to Claudius Ptolemy, where it was called Edri Deserta or in Greek Εδρου ἐρῆμος (Edrou Heremos, Edar's isolated place).

Other writers think that Edrou was actually Lambay Island, from Greek ἑδρα (hedra) "sitting place [for ships]".

[3] The cliffs support a large colony of seabirds, notably razorbills, common guillemots, fulmars, kittiwakes and cormorants.

The scrubland above supports several heathland species including skylarks, meadow pipits, common whitethroats, linnets, stonechats and whinchats.

Howth is a popular destination for day-trippers from the capital, accessible by car, bus and one of the northern termini of the Dublin Area Rapid Transit train system (DART).

In the short story 'Eveline', another work by James Joyce from the collection Dubliners, it is mentioned that Eveline and her family once had a picnic on the Hill of Howth.

Howth Head is also central to Joyce's final work, Finnegans Wake, in which one of the principal characters, HCE, is, among other things, representative of the mountain.
