Garang Mawien Kuol (born 15 September 2004) is a professional soccer player who plays as a winger for Czech First League club Sparta Prague. Born a South Sudanese refugee in Egypt, he plays for the Australia national team.

Kuol was born on 15 September 2004 in an Egyptian refugee camp, to South Sudanese parents Mawien and Antonietta Kuol. His family fled their war-torn home in South Sudan to Egypt before eventually settling in Shepparton, Victoria, Australia in 2005. Growing up in regional Victoria, Garang was first introduced to football by his brother Kuol and frequently trained with his two other brothers Teng and Alou Kuol. Both Garang and Alou took inspiration from Australian footballers Tim Cahill and Mark Bresciano. Kuol started his football as a junior for Shepparton Soccer Club, before joining Goulburn Valley Suns, where he trained in the youth and senior ranks for five years until the age of 15.

Kuol signed with Central Coast Mariners Academy in January 2021, joining his brother Alou Kuol. At the age of 16, Kuol got his first start for the senior NPL squad on 14 March, against Mounties Wanderers after the squad's main starters were absent with the A-League Men squad. In December, Kuol earned his first call-up to the A-League squad for their FFA Cup clash against Wollongong Wolves but wasn't officially named on the bench despite being with the substitute group on the day. In the subsequent round, Kuol scored on his professional debut on 21 December, just seven minutes after coming off the bench, in a 6–0 away win against APIA Leichhardt. He would miss the next game against Sydney FC due to illness. Kuol returned in the final as a late substitute where he was involved in his side's consolation goal in the seventh minute of stoppage time in a 2–1 defeat to Melbourne Victory.

Kuol made his A-League Men debut on 5 April 2022, scoring a goal with a first-time shot through Phoenix keeper Oliver Sail, in the Mariners' 5–0 win over Wellington Phoenix. His finish was praised by pundits including his brother, Alou, who stated, "Garangski has landed." Kuol went on to score three goals in his next six A-League Men appearances to secure Finals qualification. On 20 May, Kuol was one of two "Commissioner's picks" chosen to play in the 2022 A-Leagues All Stars Game against Barcelona. On 23 June, Kuol signed his first professional contract on a two-years deal with the Mariners amidst notable interests from foreign clubs. On 13 November, Kuol scored twice for the Mariners after coming on as a substitute in a 3–2 loss to Western United. His second goal, a powerful strike from a narrow angle, was named as the A-League Men's Goal of the Month for November by 10 News First, as selected by former Socceroo Alex Tobin. Kuol made his first league start for the Mariners on 18 December, managing one assist in a 2–1 win over Sydney FC, and later his last appearance for the club on 30 December in a 2–1 win against Melbourne Victory where he received a standing ovation from the fans at Central Coast Stadium.

In mid-September 2022, it was reported that Kuol had signed a pre-agreement and would transfer to English Premier League side Newcastle United during the January 2023 transfer window. On 30 September 2022, Kuol signed a four-year deal with Newcastle United for a transfer fee of £300,000 included with sell-on clauses and other bonus triggers. He officially joined the club on 1 January 2023. On 12 January 2023, Kuol was loaned to Scottish Premiership club Heart of Midlothian until the end of the 2022–23 season. He made his debut at Tynecastle Park the following day, coming on as a substitute for Barrie McKay at the 77th minute of a 1–0 league victory over St Mirren. On 1 February, Kuol started his first league game, played out of position as a midfielder instead of his natural position as a forward, in a 3–0 defeat to Rangers. He scored his first goal for the club in the next fixture against Rangers in the 4th minute of additional time after coming on as an 83rd-minute substitute to secure a 2–2 draw. Kuol returned to Newcastle in late June, making only limited appearances for Hearts.

Kuol was not added to the Magpie's pre-season in the United States, instead training in Verona with fellow Premier League academy players, Amani Richards and Sol Sidibe. While awaiting for the completion of his work permit, on 8 August, Kuol was sent on a season-long loan to Eredivisie club FC Volendam. He made his debut for the club on 12 August in a 2–1 league loss to Vitesse at Kras Stadion. In his second starting appearance, Kuol scored his first league goal for the club in a 3–1 defeat to Fortuna Sittard on 17 September 2023. He became the youngest foreigner to score in FC Volendam's history, having netted the club's third goal in four games, all of which have been defeats. He was awarded Volendam's August–September Goal of the Month for his strike against Fortuna. After the resignation of manager Matthias Kohler, Kuol faced reduced playing time under new manager and former assistant Regillio Simons, who placed tactical changes that led him to be benched. Kuol returned from loan in May 2024, having experienced relegation in the Eredivisie with Volendam.

After his return, Kuol made his non-competitive debut for Newcastle United in a friendly against Tottenham on 22 May at Melbourne Cricket Ground, during Newcastle's pre-season tour in Melbourne, Australia.

On 29 August 2025, Kuol signed a multi-year contract with Czech First League club Sparta Prague for an undisclosed fee.
