Kaznac (Serbian Cyrillic: казнац) was a court title of the state employee in medieval Bosnia and Serbia who was in charge for the treasury in the territory under his jurisdiction — kaznačina (казначина).[better source needed] The name of the title is derived from Serbo-Croatian word kazna (English: penalty). The kaznac was a financial-taxation service, translated into Latin camerarius (itself rendered "chamberlain").
In the Dečani chrysobulls, King Stefan Dečanski (r. 1321–1331) mentioned that the court dignitaries present at the Dečani assembly were the kaznac, tepčija, vojvoda, sluga and stavilac.
The title of veliki kaznac (велики казнац, "grand kaznac") was later transformed into protovestijar.
