The tolar was the currency of Slovenia from 8 October 1991 until the introduction of the euro on 1 January 2007. It was subdivided into 100 stotins (cents). The ISO 4217 currency code for the Slovenian tolar was SIT. From October 1991 until June 1992, the acronym SLT was in use.

The name tolar comes from Thaler, and is cognate with dollar. The tolar was introduced on 8 October 1991. It replaced the 1990 (Convertible) version of Yugoslav dinar at parity. On 28 June 2004, the tolar was pegged against the euro in the ERM II, the European Union exchange rate mechanism. All recalled banknotes can be exchanged at the central bank for current issue.

On 1 January 2007, the tolar was supplanted by the euro. Slovenia issues its own euro coins, like all other nations in the Eurozone.

The timescale for conversion from the tolar to the euro operated differently from the first wave of European Monetary Union (EMU). The permanent euro/tolar conversion rate was finalised on 11 July 2006 at 239.640 tolar per euro. During the first wave of EMU, this period was only a day (the conversion rates were fixed on 31 December 1998 and euro non-cash payments were possible from 1 January 1999). Also unlike the first wave of EMU which had a three year transition period (1999–2001), there was no transition period when non-cash payments could be made in both tolar and euro. The tolar was used for all transactions (cash and non-cash) until 31 December 2006 and the euro must be used for all payments (cash and non-cash) from 1 January 2007. However, as with the first wave of EMU, cash payments with the tolar could continue until 14 January 2007, but change had to be given in euro.
