Lahinja (pronounced [ˈlaːxinja]; also Lahinja pri Sredgori,[1][2] in older sources Lahina;[3] German: Lachina[4] or Lachina bei Mittenwald;[5] Gottscheerish: Lachinə[6]: 88 ) is a remote abandoned settlement in the Municipality of Semič in southern Slovenia.

If the names share the same origin, then it is derived from *Vlahinja, based on the root *Vlah and originally referring to pre-Slavic Romanized Celtic inhabitants of the area[8] but also applied to later Uskok settlers in the region.

[6]: 88  Another theory derives the name of the village from Middle High German lâchen 'to mark trees with a blaze'.

In the land registry of 1574 the village had three full farms divided into six half-farms with seven owners, corresponding to a population between 25 and 30.

[6]: 88  At this time, the economy of the village was based on raising animals, tending vineyards at Rodine, and selling firewood, logs, and wooden goods.
