Metadiscourse (MD) markers are of great importance in expressing the writers’ stance, and the use of MD markers can be diverse in different genres of writing. This study endeavors to scrutinize the use of MD markers (major groups: interactive markers and interactional markers) in research proposals by Vietnamese postgraduate students in English Applied Linguistics (EAL). A cohort of 20 EAL research proposals was analyzed using AntConc software and descriptive statistics. The results unravel that regarding interactive markers, transition markers are the most used in EAL research proposals while endophoric markers are the least commonly used. Concerning interactional markers, selfmentions markers are the most popular MD markers while attitude markers are the least popular ones used in EAL research proposals. It is further found out that the most common functions of MD markers used in EAL research proposals are to link ideas in texts and texts to readers and show the writer’s presence in the text.
