Herman Geelmuyden (born 22 January 2002) is a Norwegian football striker.
Hailing from Stabekk, he played in Stabæk Fotball from childhood.
In 2017 Stabæk signed a contract with him, to prevent him being picked up by a foreign giant's academy.
He made his first-team debut in the 2019 Norwegian Football Cup, playing all of Stabæk's four cup matches in that campaign, and also scoring a goal in the second round.
He made his league debut in June 2019 against Kristiansund.
