Metaphors are expressions that are frequently used in people's minds to explain concepts with other unrelated concepts and have a personal emphasis on learning. The purpose of this study is to determine and interpret the metaphorical perceptions of primary school pre-service teachers towards environmental pollution. The "phenomenology" research design was used in this study. The study group of this research consists of a total of 372 primary pre-service teachers. Data were collected using semi-structured forms to determine the metaphorical perceptions of primary school pre-service teachers. The pre-service teachers were asked to complete the sentence, "Environmental pollution is like... because....". At the conclusion of multiple comparisons, by the relation degree between environmental pollution and its metaphors, it was determined that significant difference was in favour of the 2nd year between the 2nd and 4th years and in favour of the 3rd year between the 3rd and 4th years. As a result of the research, it was discovered that the majority of the metaphors produced by the pre-service teachers were in the "human" and "harmful/dangerous/uncomfortable situations" categories. Furthermore, the study discovered that as the year level increased, the number of related metaphors about environmental pollution decreased.
