This bibliometric study analyzed the research topic structure of the Reading in a Foreign Language (RFL) journal in the past two decades. Using two well recognized bibliometric approaches, namely, the keyword co-occurrence analysis and hierarchical cluster analysis, the study examined author keywords and their co-occurrence of 184 research articles from 2002 to 2020. Results revealed that (1) the journal covered a wide range of reading research topics, and its most frequently researched topics were extensive reading, reading fluency, vocabulary learning, reading of foreign languages other than English, etc; (2) frequently researched topics were clustered into eight groups, including development of reading fluency, learner factors, vocabulary, etc.; and (3) the network of research topics centered around six large nodes (i.e., standardized keywords), namely extensive reading, reading fluency, vocabulary learning, reader characteristics, reading instructions, and reading comprehension. The findings might help readers and potential contributors familiarize with the research topic structure of the RFL journal. This study has important pedagogical implications
