Jakub Piotr Kiwior (born 15 February 2000) is a Polish professional footballer who plays as a centre-back or a left-back for Premier League club Arsenal and the Poland national team.
Kiwior made his professional debut in 2018 for Slovak side FK Železiarne Podbrezová, before moving to MŠK Žilina in 2019 and Spezia Calcio in 2021.
[4] Kiwior moved to the Slovak club Železiarne Podbrezová in 2018, and made his senior and professional debut with them against Nitra in the Fortuna Liga on 16 February 2019.
While Žilina grabbed a three-goal lead in the first half, Ružomberok scored two in the second period and hence Kiwior was brought on to secure the defence, as a replacement for Lukáš Jánošík.
During the coronavirus pandemic, as Žilina had entered liquidation to survive financially and had consequently released 17 players, Kiwior remained unaffected.
[11] He made his debut against Inter Milan on 1 December 2021 as a starter and gave away a penalty after handball that converted into goal by Lautaro Martínez.
He was handed his first start in a 3–1 win over Chelsea in early May after erratic performances from Arsenal's back line, owing to William Saliba's absence due to injury.
[21][22][23][24][better source needed] On 16 June 2023, Kiwior scored his first international goal in a friendly match against Germany, which Poland won 1–0.
