Francisco Fernandes da Conceição (ফ্রান্সিস্কো কোনসেইসাও) is a Portuguese professional footballer who plays as a winger for Serie A club Juventus, on loan from Primeira Liga club Porto, and the Portugal national team.

Coming through Porto's youth system, Conceição was promoted to the first-team in 2021, winning a domestic double of the Primeira Liga and Taça de Portugal in 2022. In July 2022, he moved to Eredivise side Ajax, before returning to Porto in September 2023, on an initial one-year loan deal which was made permanent at the end of the season. He joined Juventus in August 2024 on a one-year loan deal.

Conceição represented Portugal at under-16, under-17 and under-18 levels, for a total of 15 caps and three goals. In March 2021, he took part in the 2021 UEFA European Under-21 Championship, earning his first cap for the under-21 side, in a 1–0 victory in Croatia on 25 March. On 31 March, he became the youngest player (aged 18 years and 90 days) to score for Portugal in the UEFA European Under-21 Championship, after closing the 3–0 victory against Switzerland in their final match in the group phase. He would help Portugal finish as runners-up, after losing in the final 1–0 to Germany. In June 2023, Conceição took part in the 2023 UEFA European Under-21 Championship. Portugal were eliminated from the tournament, on 2 July, after a 1–0 loss to England in the quarter-finals.

On 15 March 2024, Conceição was called to the senior squad by manager Roberto Martínez for friendlies with Sweden and Slovenia. He debuted on 26 March in a friendly match against the latter that ended in a 2–0 loss.

On 21 May, he was selected in the 26-man squad for the UEFA Euro 2024. On 18 June, he came off the bench in the 90th minute, before scoring his first goal for Portugal two minutes later, which secured a 2–1 victory over the Czech Republic in the opening match. His father Sérgio had scored a hat-trick against Germany almost exactly 24 years earlier on 20 June 2000 during UEFA Euro 2000; as such they became the second father and son pair to have scored a goal in a European Championship, after the Italians Enrico and Federico Chiesa who had scored respectively in Euros 1996 and 2020. After not featuring against Turkey, he played the full 90 minutes of the final Group F fixture against Georgia which Portugal lost 2–0, before making two further appearances off the bench against Slovenia (3–0 victory in a penalty shootout) and France in the knockout stage (5–3 loss in another shootout).

Conceição's is a technical winger, with a tight turning radius, outstanding close control and an eye for playmaking in central zones. His game revolves around getting the ball into the penalty area from wide via carries and crosses. His compact build, standing at a low center of gravity coupled with quick, small strides allows him to make frequent and consistent contact with the ball while carrying it. This thereby enables him to execute constant sharp changes of directions. His agile feet also equip him with the ability to swiftly readjust himself to manipulate angles in the box, either to get shots off for himself or to set his teammates up.

Born in Coimbra, Conceição is the fourth son of former Portugal international footballer and AC Milan manager Sérgio Conceição; his older brothers Sérgio and Rodrigo are also professional footballers. In addition to his native Portuguese, Conceição also speaks French and English.
