Simen Vidtun Nilsen

Simen Vidtun Nilsen (born 3 March 2000) is a Norwegian football goalkeeper who currently plays for Ranheim.

Nilsen hails from Tistedal and made his senior debut for Tistedalen in the 2018 Norwegian Fourth Division. In mid-2018 he joined Sarpsborg 08 as a youth player. He was drafted into the senior team in 2020. However, he did not play matches in any competition in 2020 due to the COVID-19-related lockdowns of football in Norway.

Nilsen made his Sarpsborg 08 debut in the 2021 Norwegian Football Cup against Kvik Halden, followed by his Eliteserien debut in December 2021 against Brann.

Nilsen won the spot as Sarpsborg 08's first-choice goalkeeper in the summer of 2022, when Anders Kristiansen sustained a thumb injury. Nilsen was placed in the starting eleven against Aalesund only 15 minutes before the game started, but continued playing in the following months. Nilsen also penned a new contract until the summer of 2025. In July 2022, Nilsen was sent off, this time paving the way for Leander Øy's debut.

In 2023, Sarpsborg 08 did not favor starting with Nilsen, and sent him on loan to Skeid for the entire 2023 1. divisjon campaign. While the team languishing in the bottom of the table, Nilsen gained experience as their near-undisputed first-choice goalkeeper. He was bought by another 1. divisjon team Ranheim ahead of the 2024 season.
