This paper offers a retrospective narrative review of research on L2 writing strategies and a prospective discussion of potential theoretical and pedagogical relevant lines of inquiry to be explored in future research agendas. The retrospective analysis will synthesize the main trends observed in the conceptualization of writing strategies as well as central directions followed in empirical research in the domain. The prospective discussion tries to advance research agendas on the basis of several observations about L2 writing that are presented as key points to be considered when analyzing existing or thinking about future research in the domain. Special mention will be made of future research avenues centrally concerned with theoretical and empirical questions on the manner in which strategic behavior during writing and during written corrective feedback processing may foster language learning. It will be suggested that following this route can result in interesting and profitable synergies between research on language learning strategies and recent SLA-oriented L2 writing research initiatives on the language learning potential associated with L2 writing.
