Jakub Piotr Moder (born 7 April 1999) is a Polish professional footballer who plays as a midfielder for Premier League club Brighton & Hove Albion and the Poland national team.

Moder was named in Poland's 26-man squad for Euro 2020 on 17 May 2021, with the tournament taken place in the summer of 2021 due to the previous year's postponement as a result of Coronavirus. Moder came on as an 85th minute substitute for Leeds United's Mateusz Klich in Poland's opening game against Slovakia on 13 June, where The Poles lost 2–1 at the Krestovsky Stadium in Saint Petersburg. He started in Poland's second group match against Spain on 19 June, where he gave away a penalty and was booked. However, Gerard Moreno hit the post, and the match eventually finished at 1–1 at Estadio de La Cartuja in Seville. Moder along with Jan Bednarek of Southampton were out injured for Poland's decisive match against Sweden on 23 June, where Poland lost 3–2 in Saint Petersburg, ending their tournament and finishing bottom of Group E.

Moder was not selected for the 2022 FIFA World Cup due to suffering an injury whilst playing for Brighton that ruled him out for over one year.
