Ystrad Tywi (Welsh:[ˈəstradˈtəwi], Valley of the river Towy) is a region of southwest Wales situated on both banks of the River Towy, it contained places such as Cedweli, Carnwyllion, Loughor, Llandeilo, and Gwyr (although this is disputed). Although Ystrad Tywi was never a kingdom itself, it was historically a valuable territory and was fought over by the various kings of Dyfed, Deheubarth, Seisyllwg, Gwynedd, Morgannwg and the Normans.
