Odysseas Vlachodimos (Greek: Οδυσσέας Βλαχοδήμος, born 26 April 1994) is a professional footballer who plays as a goalkeeper for Premier League club Newcastle United.

With back-up 'keeper Mitchell Langerak out injured, Vlachodimos was included in Stuttgart's match day squad and was brought on as a substitute following the sending off of first-choice goalkeeper Przemysław Tytoń.

[12] Having spent the majority of the first half of the following season behind regular keeper Luke Steele, Vlachodimos was handed his second start on 27 November and was named man of the match for his performance in a 1–1 draw against Panionios.

[17] After he arrived in Lisbon, fellow teammate Bruno Varela seemed to be the first-choice goalkeeper for the 2018–19 season, but Vlachodimos' overall performance in the pre-season convinced manager Rui Vitória to promote him to the starting spot.

[18] That season, Vlachodimos was included in UEFA's Champions League breakthrough team of 2018 for making a "string of impressive saves" and being "one of Benfica's brightest sparks in a testing group stage campaign".

[19] On 3 February 2019, after 20 consecutive appearances with the club in Primeira Liga, he faced a red card as the last player for a foul committed to Bas Dost in a 4–2 away win over Lisbon rivals Sporting CP.

[20] Two weeks later, in the first leg of the UEFA Europa League round of 32 match against Galatasaray, Vlachodimos made a crucial save in the 85th minute to deny Christian Luyindama the equalizer, helping Benfica secure their first win in Turkey (2–1).

[24] On 5 October 2020, with the save of two consecutive penalty kicks from Ryan Gauld helped his team prevail over Farense with a score of 3–2, achieving the third victory in an equal number of matches in the beginning of the 2020-21 season.

On 26 August 2021, Benfica qualified for the UEFA Champions League group stage after defeating PSV Eindhoven, a justification for the international Greek goalkeeper who in the summer was a step away from "Da Luz".

According to the Portuguese outlet O Jogo, Benfica could be battling to keep hold of their star goalkeeper with Newcastle United eyeing a January swoop for the Greek international.

[28] On 26 January 2022, the Portuguese press praised Vlachodimos for his performance in the victory of Benfica over Boavista in the 2021–22 Taça da Liga final, where the Greek goalkeeper was voted man of the match.

[37] He made one more appearance for the U15's against Poland the following month before making his U16 debut in August, starting in a 4–2 win over Switzerland in new manager Steffen Freund's first match in charge at the 2009 U16 Tournament in Liechteinstein.

[47] On 9 November 2018, four days after FIFA's approval of Vlachodimos' request to play for Greece,[48] he was called up by Angelos Anastasiadis for the matches against Finland and Estonia in the UEFA Nations League.
