Original KooGa vintage rugby jersey Scarlets 2008/09

The Scarlets (Welsh: Y Scarlets) are one of four professional Welsh rugby teams and are based in Llanelli, Wales. Their home ground is the Parc y Scarlets stadium. They play in the United Rugby Championship and in European Professional Club Rugby competitions. The club was originally called the Llanelli Scarlets, but was renamed at the start of the 2008–09 rugby season.

The Llanelli Scarlets were founded in 2003 as one of five (now four) regional teams established by the Welsh Rugby Union (WRU). The Scarlets are affiliated with a number of semi-professional and amateur clubs throughout the area, including Welsh Premier Division clubs Llanelli RFC, Carmarthen Quins RFC and Llandovery RFC. During the 2007–08 season they played most of their matches at Stradey Park in Llanelli, but they also played matches at the Racecourse Ground in Wrexham. The club's new stadium, Parc y Scarlets (English: Scarlets Park), was built in nearby Pemberton and opened in November 2008.

The Scarlets won the league twice: the inaugural Celtic League season 2003–04 and the Pro12 in 2016–17, beating Munster 46–22 in the 2017 Pro12 Grand Final.
