This study aimed to investigate the impact of pre-speaking activities on Iranian intermediate English as a Foreign Language (EFL) learners' oral performance. The study followed a quasi-experimental design in which subjects of the study were non-randomly selected. Oxford Placement Test (OPT) was used to select 100 intermediate EFL learners as the main sample. Then they were divided randomly into two experimental and control groups. Prior to the treatment, participants of both groups were given a pretest of speaking to ensure their speaking ability. After a treatment of pre-speaking activities to members of the experimental group, a posttest of speaking was administered to seek the effect of it. A t-test was run to examine the difference between the mean scores of each group in posttests. It was found that there was a statistically significant difference between the experimental and the control group. That is, the experimental group outperformed the control group in oral performance.
