Oliver Christensen (born 22 March 1999) is a Danish professional footballer who plays as a goalkeeper for Italian Serie B club Salernitana, on loan from Fiorentina.

Christensen also made key contributions in the Coppa Italia, performing strongly in both the round of 16 against Parma and the quarter-finals against Bologna.

[17] In his second season, following the arrival of David de Gea, Christensen became the fourth-choice goalkeeper and was left entirely out of the squad by new head coach Raffaele Palladino.

After gaining a cap for the under-20 side in 2019, Christensen made his debut for the under-21 team on 10 September 2019 in a 2–1 victory in the 2021 UEFA European Under-21 Championship qualification match against Romania in Aalborg.

[22] On 9 November 2020, Christensen was called up to Kasper Hjulmand's senior squad for the friendly against Sweden due to several cancellations from, among others, the Danish national team players playing in England, due to the COVID-19 restrictions, as well as a case of COVID-19 in the squad, which had put several national team players in quarantine.
