Isak Tomar Hjorteseth (born 14 March 2004) is a Norwegian footballer who plays as a midfielder for Sandnes Ulf on loan from Brann.
He started his youth career in Mathopen, where he remained until the club struggled to field a boys' team. Hjorteseth then went on to FK Fyllingsdalen.[1] Hjorteseth made his international youth debut for Norway U15 in 2019.
Ahead of the 2021 season he joined SK Brann together with Fyllingsdalen teammate Niklas Jensen Wassberg. The intention was to loan Hjorteseth back to Fyllingsdalen, which happened in the summer of 2021.[1] He scored his first Brann goal in October 2022, as the club bounced quickly back to Eliteserien after being relegated the year before.[2] Hjorteseth made his Eliteserien debut in April 2023 against Odd. In the summer window of 2023, Hjorteseth was sent on loan to Åsane. After scoring his first goal for Åsane, manager Morten Røssland called Hjorteseth a "gift from God".[3] In 2024, another loan of Hjorteseth was orchestrated, this time to Sandnes Ulf. The intention was to use Hjorteseth as a regular, and make him a "leading star" in the team.[4]
