Original Under Armor vintage rugby shirt Wales 2019/20

The Wales men's national rugby union team represents Wales in the international men's rugby union. The governing body, the Welsh Rugby Union (WRU), was founded in 1881, the same year that Wales played their first international match against England. The team plays its home games at the Millennium Stadium in Cardiff (currently known as the Principality Stadium for sponsorship reasons), which replaced Cardiff Arms Park as Wales' national stadium in 1999.

Wales has competed in the Six Nations Championship (formerly the Home Nations Championship and Five Nations Championship) annually since its formation in 1883. They have won the tournament (and its predecessors) 28 times, most recently in 2021. Since the Six Nations was founded in 2000, Wales have won six Six Nations titles, including four Grand Slams, and have finished bottom once. Wales have also competed in every Rugby World Cup since the competition was founded in 1987; they finished third in the opening tournament and have since reached two semi-finals, in 2011 and 2019. Wales hosted the 1999 Rugby World Cup, although matches were also played in England, Scotland, Ireland and France.
