Alfa Semedo Esteves (born 30 August 1997) is a Bissau-Guinean professional footballer who plays as a midfielder for English club Reading on loan from Benfica.
Born in Bissau, Semedo started playing football at local club Fidjus di Bideras. In 2014, aged 16, he moved to Portugal and joined Benfica's youth system. After playing two years for their juniors team, he was loaned out to Vilafranquense in Campeonato de Portugal for one season. On 8 July 2017, he signed a four-year contract with Moreirense in Primeira Liga, with whom he would make his professional debut in a Taça da Liga match against Desportivo das Aves on 30 July that year.
Following his return to Benfica in July 2018 for €2.5 million, Semedo debuted for the first team in a 3–2 home win over Vitória de Guimarães in Primeira Liga on 10 August. Later, on 2 October, he made his UEFA Champions League debut, scoring his first and winning goal for Benfica in a 3–2 away victory over AEK Athens in the UEFA Champions League group stage, thus ending the former's eight-match losing streak in the competition's group stage.
On 31 January 2019, Semedo was loaned out to La Liga side RCD Espanyol until June. On 8 July, he joined English club Nottingham Forest on a season-long loan, along with Benfica teammate Yuri Ribeiro (the latter on a permanent transfer). He scored his first goal for the club in a 1–0 away win over Swansea City on 14 September 2019.
