Justin Bijlow (born 22 January 1998) is a Dutch professional footballer who plays as a goalkeeper for Eredivisie club Feyenoord and the Netherlands national team.

In January 2016, he travelled with the first team for a training camp in Albufeira and was included in Feyenoord's match squad for the first time, for the away game against AZ in the Eredivisie.

Bijlow was an unused substitute as Feyenoord beat Vitesse on penalties to win the Johan Cruyff Shield on 5 August 2017.

[8] Eight days later, he made his professional debut, starting in Feyenoord's 2–1 win against FC Twente in the opening round of the Eredivisie after first-choice goalkeepers Brad Jones and Kenneth Vermeer both got injured.

Bijlow started the final two league games, which resulted in 3–1 and 2–3 wins over Sparta Rotterdam and Heerenveen, saving a penalty kick in the latter.

[12] He made his debut in international competition five days later as Feyenoord lost 4–0 to AS Trenčín in the UEFA Europa League third qualifying round.

[15] After Dick Advocaat replaced Stam as Feyenoord head coach in October 2019, Vermeer remained first-choice goalkeeper.

[21] A day later, during a 5–0 win against Elfsborg in the UEFA Europa Conference League play-off round, Bijlow got sent off with a red card for the first time in his career.

[24] In January 2023, Bijlow went viral after getting booked for throwing a ball onto the pitch to stop play and avoid potential goal threat from FC Twente during a 1–1 draw in the Eredivisie.

[29] He suffered a calf injury during Feyenoord's 0–1 win against AZ, his hundredth Eredivisie game, on 4 February 2024 and was sidelined for the following two months.

[31] Ahead of the 2024–25 season, new head coach Brian Priske picked Timon Wellenreuther rather than Bijlow as first-choice goalkeeper in what he called "a luxury problem.

"[32] On 4 August 2024, Bijlow was an unused substitute as Feyenoord beat PSV in a penalty shoot-out to win the Johan Cruyff Shield.

After Bijlow was also included in the Netherlands' squad for the knock-out stage of the tournament in May 2021, he started in the quarter-final against France (2–1 win) and the semi-final against Germany (1–2 defeat).

[48] He was called up to the national team for the first time in November 2020 by Frank de Boer to replace the injured Jasper Cillessen, but subsequently had to withdraw with an injury.

In November 2022, Louis van Gaal announced that Bijlow would be part of the 26-men squad at the 2022 FIFA World Cup in Qatar.

In June 2023, Bijlow said that his former goalkeeping team mates Brad Jones and Kenneth Vermeer helped him the most during his career, especially for high balls, saving one-on-one chances and staying calm.

Bijlow named leading a defense and a team, saving shots on the goal line and distributing with his feet as his qualities.

[60] In June 2023, Bijlow named Iker Casillas as his idol as a kid and Manuel Neuer and André Onana as all-time goalkeepers he wanted to train with.
