Lokavec (pronounced [lɔˈkaːʋəts]) is a settlement on the northern edge of the Vipava Valley northwest of Ajdovščina in the Littoral region of Slovenia.

The name is derived from the adjective *lǫkavъ 'twisted, winding' or from the common noun *lǫkava 'curve, twist', perhaps originally a hydronym.

[5] The discovery of Celtic grave sites in Lovavec shows that it was already settled in prehistoric times.

The Celtic settlement there had a defensive structure built on Gradišče Commons Hill (Slovene: Gradiška gmajna, elevation: 215 meters or 705 feet) in neighboring Ajdovščina.

[4] Lokavec is the site of a mass grave from the period immediately after the Second World War.
