The issues of humor and collocation are among the themes that have recently attracted the attention of researchers in language pedagogy. In line with this current trend of research, this study investigated the effect of reading humorous texts on learning collocations by Iranian EFL learners. To achieve this end, 59 Iranian EFL students majoring English Literature and English Translation were selected as the participants, and their language proficiency and knowledge of collocation were determined via Success Test and Collocation tests. They were given a pre-test (in order to determine their knowledge of specific collocations used in humor texts), five tests with five humor texts, and a post-test (in order to find the effect of reading humor texts on learning collocations). Paired sample t-tests and ANOVA were then employed to analyze the collected data. The findings of the study revealed that humor texts can bear positive impacts on collocation learning of Iranian EFL learners. The findings of the study can have implications for teaching collocations.
