The three unnamed individuals were accused of moral corruption, the state-run news agency ISNA said, adding that all three were given 100 lashes.
Both the men were lashed in a town square in public, a local prosecutor was quoted as saying, while the woman was lashed in a different location.
Under Irans Islamic Penal Code, adultery by a married woman is punishable by flogging and stoning. The law is very specific about the manner of execution and types of stones which should be used. Article 102 states that men will be buried up to their waists and women up to their breasts for the purpose of execution by stoning. Article 104 states, with reference to the penalty for adultery, that the stones used should not be large enough to kill the person by one or two strikes, nor should they be so small that they could not be defined as stones.
