'''Llywelyn ap Gruffudd''' ({{Circa|1223}} – 11 December 1282), also known as '''Llywelyn II''' and '''Llywelyn the Last''' ({{langx|cy|Llywelyn Ein Llyw Olaf|lit=Llywelyn, our last leader}}), was [[List of rulers of Gwynedd|Prince of Gwynedd]], and later was recognised as the [[Prince of Wales]] ({{langx|la|Princeps Walliae|links=no}}; {{langx|cy|Tywysog Cymru|links=no}}) from 1258 until his death at [[Cilmeri]] in 1282. Llywelyn was the son of [[Gruffudd ap Llywelyn ap Iorwerth]] and grandson of [[Llywelyn ab Iorwerth]] (also known as Llywelyn the Great, or Llywelyn I), and he was one of the last native and independent princes of Wales before its [[Conquest of Wales by Edward I|conquest]] by [[Edward I of England]] and [[English rule in Wales]] that followed, until [[Owain Glyndŵr]] held the title during his [[Glyndŵr rebellion|rebellion]] of 1400–1415.
