Llenyddiaeth mewn Theori is a Welsh-medium academic journal published annually with the support of academics in university departments throughout Wales. Dr Owen Thomas (University of Swansea) is its editor; the consultative editor is Professor John Rowlands (University of Bangor) and the Editorial Board is composed of research-active members of staff in academic Welsh departments.

Each issue offers scholarly full-length articles in the field of Welsh literature, often but not exclusively from a theoretical perspective. Among its contributions are proceedings drawn from the one-day conference held annually at the University of Wales, Lampeter. All articles are peer reviewd by the Editor, Consultative Editor and members of the Editorial Board. All articles are in Welsh with English abstracts.
