This study investigated the use of metadiscourse tools by Saudi and British authors in Applied Linguistics discipline. In particular, the study tried to identify the kinds of metadiscourse markers used by Saudi and English authors in ALRAs and to determine the most and least frequent metadiscourse makers. In order to achieve these goals, (10) ALRAs written by Saudi authors and (10) ALRAs written by British authors served as the corpus of the study. The research articles were selected from well-known journals and published between 2010 -- 2018. Hyland's (2005) model was used to find out the distribution of metadiscourse markers in each type of corpora. The findings showed interactive metadiscourse markers are used more than the interactional metadiscourse markers. Compared with the British authors, the Saudi authors were found to use metadiscourse markers more than the British authors. The Saudi authors employed all metadiscourse sub-categories more frequently than the British authors except frame markers, evidentials, endophoric markers, and self-mentions. In addition, it was found that transitions were the highly frequent metadiscourse markers in the whole corpora, followed by hedges, evidentials, boosters, and attitude markers, respectively. On the other hand, engagement markers were the least frequent metadiscourse markers in the whole corpora.m
