The present study aimed to review the instruction of the L2 speech acts in English pragmatics in the Iranian context during the last two decades from 2000 to 2020. To this end, upon the completion of the study search, the retrieved articles were selected and analyzed based on the research domain. The results of our synthesis from 54 studies carried out on the instruction of the speech act not only reveal that pragmatics is amenable to instruction but also unfold that the most frequently instructed speech act is the speech act of request which has been conducted in 29 studies, while the least instructed speech act is invitation, used in only one study. Moreover, analyzing the data collection methods documented that Multiple-choice Discourse Completion Test (MDCT) is the most predominant method utilized in 36 papers during the last decades in English pragmatic instruction. With respect to the treatment types, it is illuminated that the most recurrent treatment type is explicit, implicit vs. control, followed by explicit vs. implicit, although other treatment types have been embarked on. As a final point, it is worth noting that 53 of the conducted studies utilized the quantitative method in their data analyses, whereas only one study implemented the qualitative method. The paper concludes with some avenues for further research.
