The somoni (ISO 4217 code: TJS) is the currency of Tajikistan. It is subdivided into 100 diram. The currency is named after the father of the Tajik nation, Ismail Samani (also spelled Ismoil Somoni).

The somoni was introduced on 30 October 2000; it replaced the Tajikistani ruble, at the rate of 1 somoni = 1000 rubles and 1 diram = 10 rubles. Diram banknotes were first introduced on 30 October 2000 to start the currency off and coins were introduced later in 2001 with the intention of creating a more efficient monetary system and gradually replacing the diram notes. This was also the first time circulating coins were introduced in Tajikistan.

Coins - 1, 2, 5, 10, 20, 25, 50 diram, 1, 3, 5 somoni.

Banknotes - 1, 5, 20, 50 diram, 1, 3, 5, 10, 20, 50, 100, 200, 500 somoni.
