The flag of Saint David (Welsh: Baner Dewi Sant) represents the 6th-century Saint David (Welsh: Dewi Sant; c. 500 – c. 589), a Welsh bishop of Menevia and the patron saint of Wales.
Saint David's cross has been used as a flag to represent Wales, as a less frequently used alternative to the Red Dragon flag. England and Scotland primarily use patron saint flags of Saint George and Saint Andrew, respectively.
It is similarly used in the Diocese of St Davids arms. On Saint David's Day it often plays a central role in the celebrations.
