Llwyn-y-Brain is a small Roman auxiliary fort located in the upper Severn valley near Caersws in mid-Wales, likely active during the late 1st and early 2nd centuries AD as part of the Flavian-Trajanic military network. It would have housed a detachment of auxiliary troops, probably no more than a quingenary cohort, and functioned as a marching or temporary campaign base rather than a long-term garrison post.

The site forms part of the dense system of forts, fortlets and marching camps established to control the Welsh interior following the Roman conquest of the Ordovices under Agricola, lying on or near the road network linking Caersws to the Severn headwaters and onwards toward Pennal and the Wroxeter hinterland.
Little detailed excavation has been undertaken at Llwyn-y-Brain, with the site known primarily through aerial photography and earthwork survey revealing the characteristic playing-card outline; surface finds and limited trenching have produced modest quantities of Roman military material consistent with short-lived occupation.
