'''Eskiætt''' ([[fræðiheiti]]: ''Fraxinus'') er ættkvísl blómstrandi trjáa af [[smjörviðarætt]] (''Oleaceae''). Hún er með um 45–65 tegundir af meðalstórum til stórum trjám, yfirleitt lauffellandi, þó örfáar tegundir í heittempruðum svæðum eru [[sígræn]]ar. Ættkvíslin er útbreidd um mestalla Evrópu, Asíu og Norður Ameríku.<ref name="ashley">{{cite web |url=http://apps.kew.org/wcsp/namedetail.do?name_id=369462 |title=Fraxinus |work=World Checklist of Selected Plant Families |publisher=Kew Royal Botanical Gardens |accessdate=16 April 2016 |archive-date=16 október 2012 |archive-url=https://web.archive.org/web/20121016140710/http://apps.kew.org/wcsp/namedetail.do?name_id=369462 |url-status=dead }}</ref><ref>{{cite web |url= http://luirig.altervista.org/flora/taxa/floraspecie.php?genere=Fraxinus |title=''Fraxinus'' |work=Altervista Flora Italiana |accessdate=16 April 2016}}</ref><ref>{{cite web |url= http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=113002 |work=Flora of China |volume=15 |pages=273 |via= 衿属 qin shu |title=''Fraxinus'' Linnaeus, Sp.
