Gwenllian ferch Gruffudd ([ɡwɛnˈɬiːan vɛrχ ˈɡrɨ̞fɨ̞ð] ⓘ, died 1136) was a 12th-century Welsh rebel. The daughter of Prince of Gwynedd Gruffudd ap Cynan and member of the House of Aberffraw, she married Gruffudd ap Rhys, the Prince of Deheubarth, and led a "patriotic revolt" with him during the Great Revolt of 1136 until her death at the battle at Kidwelly Castle.
Her death would serve as a rallying cry for Welsh rebels, and she became a symbol of Welsh independence. There are several notable artistic depictions of Gwenllian, often depicting her with a sword in hand, or riding a chariot into battle in the style of Boudicca. She is sometimes confused with Gwenllian ferch Llywelyn, who lived two centuries later.
