Despite the importance of replication research in scientific fields, very few replications are conducted in applied linguistics (AL). To enhance language researchers’ awareness of replications and provide a systematic evaluation of current replications, this study analyzed replication studies published in 92 AL leading journals from 1970 to 2021 based on five themes of replication labels, methodological orientations, research trends, authorship, and citation counts of replicators. The results reveal that replication labels have explicitly been mentioned since 2002, the replication of quantitative studies has predominately been raised, studies on second language acquisition were frequently replicated, collaborative authorship has increased in replications, and influential AL scholars tend to conduct replication research. The study highlights the need for a well-established replication classification and calls for replication research in the areas and methodological orientations marginalized in AL. It is also recommended that prominent figures perform more replication research to consolidate its status in AL.
