Hörgársveit (Icelandic pronunciation: [ˈhœrkˌaurˌsveiːt] ) is a municipality located in north-central Iceland, in Northeastern Region. Its seat is the village of Lónsbakki [ˈlounsˌpahcɪ].

The former municipality of Hörgárbyggð [ˈhœrkˌaurˌpɪɣθ] was formed on 1 January 2001 by the union of the municipalities of Skriða [ˈskrɪːða] (Skriðuhreppur [ˈskrɪːðʏˌr̥ɛhpʏr̥]), Öxnadalur [ˈœkstnaˌtaːlʏr̥] (Öxnadalshreppur [ˈœkstnaˌtalsˌr̥ɛhpʏr̥]) and Glæsibær [ˈklaiːsɪˌpaiːr̥] (Glæsibæjarhreppur [ˈklaiːsɪˌpaiːjar̥ˌr̥ɛhpʏr̥]). In 2010 Hörgárbyggð merged with the municipality of Arnarnes [ˈa(r)tnarˌnɛːs] (Arnarneshreppur [ˈa(r)tnarˌnɛsˌr̥ɛhpʏr̥] ) to form the current municipality of Hörgársveit.

Located on the Eyjafjörður, to the north of Akureyri, Hörgársveit is made up of several villages, principally Þelamörk [ˈθɛːlaˌmœr̥k], Lónsbakki (115 inhabitants) and Hjalteyri (37 inhabitants), the seat of the former municipality of Arnarnes.
