Reiss Luke Nelson (born 10 December 1999) is an English professional footballer who plays as a winger for Premier League club Fulham, on loan from Arsenal.

Born in London, Nelson joined Arsenal's academy when he was nine years old and gradually made his way to the first-team, regularly playing above his age group.

After gaining experience at German side TSG Hoffenheim during the 2018–19 season, he returned to Arsenal where new manager Mikel Arteta used Nelson sparingly due to injury.

[8] Ahead of Arsenal's 2017–18 season, Nelson was named in Arsène Wenger's pre-season touring squad travelling to both Australia and China.

[9] On 13 July 2017, he made his unofficial debut for Arsenal against Sydney FC in a friendly; during the game Nelson played on the right-wing, dribbling balls towards the byline and setting up teammates Joe Willock and Danny Welbeck regularly.

[13] Nelson made his first competitive appearance against Chelsea in the 2017 FA Community Shield; he came on as a substitute for Welbeck as Arsenal won 4–1 on penalties after the match had ended in a draw.

[16] With fellow winger Alexis Sánchez having left Arsenal, it was speculated that Nelson could get an extended run in the first-team in his absence;[17] however, he only made two more Premier League appearances during the season.

[21] Nelson scored six Bundesliga goals in his first seven appearances for Hoffenheim,[22] including a wide curling strike against Bayer Leverkusen in November.

He was brought into the first team along with fellow academy graduate Emile Smith Rowe as Emery looked to focus on youth talent in his second season;[25] he was also given the number 24 shirt.

[31] Nelson scored against Leeds United in Arsenal's 1–0 win in the FA Cup third round in January 2020,[32] but was injured later in the month;[33] he returned from injury against Portsmouth in March.

In Arsenal's 2020 FA Community Shield match against Liverpool, Nelson came on as a substitute, taking and scoring the first penalty in a shootout win after the game ended 1–1.

[38] He only made nine appearances during Arsenal's 2020–21 campaign;[39] injuries hindered Nelson during the season, limiting him to just 69 minutes of Premier League football.

[43] Nelson scored four goals for Feyenoord during his time at the club;[44] he also helped his side reach the inaugural UEFA Europa Conference League final, which they lost 1–0 to José Mourinho's Roma in Tirana, Albania.

[55] Despite just signing a long-term contract, it was speculated that Nelson might leave Arsenal in the 2024 Summer transfer window, as he made only one Premier League start for the club during the entire season.

Three days later, he scored his first goal for the club against Preston North End in the third round of the EFL Cup, a tie Fulham lost 16–15 in a penalty shootout after drawing 1–1.
