Oliver Provstgaard Nielsen (; born 4 June 2003) is a Danish professional footballer who plays as a centre-back for club Lazio, and the Denmark national team.
Born in Copenhagen, Provstgaard moved to Vejle at the age of four and joined Vejle Boldklub from Bredballe IF at under-13 level. He progressed through the club's youth system and was first named in the senior matchday squad on 7 October 2020 for a Danish Cup match against Hobro, although he remained an unused substitute.
In December 2020, Provstgaard suffered a serious knee injury in an under-19 match, which required surgery and kept him out for several months. Despite the injury, Vejle announced on 7 June 2021 that he had signed a new contract running until June 2024, effective from 1 January 2022, when he was also due to become a permanent member of the first-team squad. Provstgaard later said that the rehabilitation period had strengthened him both physically and mentally. Amid an injury crisis in Vejle's defence, Provstgaard made his first-team debut on 14 April 2022, playing the full match in a 2âÂÂ1 defeat to OB in the Danish Superliga. On 27 May 2022, he signed a further contract extension until June 2026.
On 3 February 2025, Provstgaard joined Italian Serie A club Lazio. According to media reports, he signed a contract running until June 2029.
Provstgaard has represented Denmark at youth international level from under-16 to under-21 level. He made three appearances and scored once for the under-16 team in 2019, before making nine appearances for the under-17s between 2019 and 2020.
He was first called up to the Denmark under-21 team in November 2022 by head coach Jesper Sørensen, and made his debut on 17 November, replacing Alexander Busch in a 2âÂÂ2 friendly draw with Sweden.
Provstgaard later captained the under-21 side on several occasions in the absence of Maurits Kjærgaard, first doing so in a 0âÂÂ0 draw against the Czech Republic on 17 October 2023. He again wore the armband in a 3âÂÂ0 win over the Lithuania under-21 team on 26 March 2024, played at Vejle Stadium.
In March 2026, Provstgaard received his first call-up to the senior Denmark squad from head coach Brian Riemer for the 2026 FIFA World Cup qualification play-off against North Macedonia. He made his senior debut in the 4âÂÂ0 victory, replacing Christian Nørgaard in the 86th minute.
Provstgaard is a prolific Esports player, winning the 2021 eChampions League and a $75,000 prize.
