Rhys Patchell (born 17 May 1993) is a Wales international rugby union player. A fly-half, he currently plays for the Highlanders in Super Rugby, having previously played for the Scarlets and Cardiff Blues. Patchell represented Wales on 22 occasions between 2013 and 2023.

Educated at Ysgol Gymraeg Melin Gruffydd and at Ysgol Gyfun Gymraeg Glantaf. Patchell speaks Welsh, and is an ambassador for the Tafwyl festival.

Patchell graduated from the Blues Academy into the full regional side at an early age in 2012. He went on to score more than 600 points in a five-year stint at the Arms Park that saw him make 83 appearances. He scored 174 points in the 2015/16 season to top the Guinness Pro12 charts.

Patchell joined Scarlets in 2016; it proved to be a shrewd move, as he ended his first season as the leading points scorer in the Guinness Pro12 once again with 145. Patchell picked up a winners' medal, helping the west Walians beat Munster in the 2017 Pro12 Grand Final at the Aviva Stadium.

Patchell suffered a series of injuries between 2019 and 2021, limiting his involvement with both the Scarlets and Wales. He returned to full fitness in early 2022, featuring frequently for the Scarlets during the latter half of their season, and continuing his involvement into the 2022–23 United Rugby Championship.

On 21 April 2023, it was announced that Patchell would depart the Scarlets at the end of the season.

Patchell signed for Super Rugby club the Highlanders on 12 July 2023.

In January 2013, Patchell was selected in the Wales U20 squad for the 2013 U20 Six Nations Championship.
