Media diplomacy is one of the tools that in the age of communications could be considered as a means of executing soft power and serving national interests. Therefore, employing media diplomacy by Iran as a regional power is of utmost importance. In this regard, effect of Iran’s media diplomacy in Afghanistan on attracting Afghan audience is a topic of consideration. The purpose of this research is to examine the success of media diplomacy employed in Afghanistan in the field of attracting Afghan audience. In this research three hypotheses are mentioned, one of which have been rejected and the other two have been proved. This hypothesis which is: Iran appears to have succeeded in attracting the Afghan audience towards her policies in Afghanistan; has been rejected. Two other hypotheses such as: a) It seems that Iran has been unable to use the two countries’ common language to its full advantage in dispelling Afghanistan’s potential threats; b) Iran’s media diplomacy seemingly has been unsuccessful in attracting and encouraging Afghan media to reflect Iran’s views and outlook, have been proved. The result of assessing statistical data generally shows that Iran has not employed a suitable strategy in relation to her media diplomacy in Afghanistan to attract of Afghan audience.
