The concept of Communities of Practice (CoPs) has attracted interest for over two decades and has been actively re-examined from a variety of perspectives, especially in the field of education. However, limited research has been conducted into the concept of one EFL classroom-based teaching and learning community constituting one CoP. This paper discusses the potential applicability of the concept of CoPs to the EFL classroom and investigates the following question: "Can a certain number of students and their instructor participating in a group population be defined as a CoP?" The results of the study showed that considering an EFL classroom in its entirety as a CoP is possible, and an expansion of the definition of CoPs to include EFL pedagogical communities is necessary.
