Troščine (pronounced [tɾɔˈʃtʃiːnɛ]; in older sources also Trošine,[2] German: Troschein[2][3]) is a small village north of Polica in the Municipality of Grosuplje in central Slovenia.

The name is believed to derive from the Slovene common noun trušec 'official responsible for the table' (from Old High German *truh(t)sâʒ(ʒ)o), thus meaning 'settlement where an official lives'.

[6] The name Špaja vas was first attested in written sources in 1710 as Supaina vaſs (and as Shpanjavaſs in 1720 and ex Spane vaſsi in 1780).

Before the Second World War, the economy of the village was based on agriculture, and the sale of cattle, pigs, timber, and firewood.

[7] On 20 March 1943 the bodies of five murdered men, known as the Dobrunje and Bizovik victims, were discovered buried in Krčmar's Woods (Slovene: Krčmarjeva hosta) south of Troščine.
