伊朗里亞爾（波斯語：ریال；貨幣編號IRR；標誌：﷼）是伊朗目前的流通貨幣。輔幣單位第納爾。1里亞爾=100第納爾。然而在一般日常生活中，伊朗人習慣以土曼（تومان/toman）來標示價錢，1土曼=10里亞爾。
由於伊朗因為近期核問題，及油價下跌影響（伊朗82%出口為石油），因此貶值快速，2019年10月1日時，1美元可兌換42,016伊朗里亞爾[7]。已有10,000舊貨幣換1新貨幣的想法，但目前一直維持當前貨幣流通。
2016年12月，伊朗政府宣布該國的貨幣將從里亞爾（Rial）更改為常用的土曼（Toman）。此舉需伊朗議會批准。2019年，伊朗政府部長通過了一項法案，要求去掉四個零，並將一個土曼重估為等於10000里亞爾，而不是之前的十里亞爾。
2020年5月4日，伊朗议会投票通过《伊朗货币和银行法》修正案，将官方货币改为“土曼”（Toman），1万里亚尔兑换1土曼[8][9][10][11]。
