Rial (ریال in Persian; ISO 4217 code IRR) is the official currency of Iran. It officially consisted of 100 dinars, but the rial is so small these days that no fraction of the rial is used in accounting anymore.

The rial replaced an older currency known as the toman. One toman is worth 10 rials, and although the currency was changed to the rial in the early 20th century, the term toman still enjoys wide usage among Iranians today. Most Iranians think in tomans when discussing money.

There is no official symbol for the currency, but the Iranian standard ISIRI 820 defined a symbol for use on typewriters, and the two Iranian standards ISIRI 2900 and ISIRI 3342 define a character code to be used for it. The Unicode Standard has a compatibility character defined for "RIAL SIGN" [﷼] at the position U+FDFC
