Trondheim Spektrum (formerly Nidarøhallen) is a multi-purpose indoor arena in Trondheim, Norway. It is located on the peninsula of Øya next to the Nidelven river. It is the home arena for men's basketball team Nidaros Jets and the alternate arena for Kolstad Håndball when playing EHF Champions League matches. A new arena was completed in 2019 and replaced the largest multi-use hall in the same location. The eight former halls originally went by the name Nidarøhallen.
Next to the halls is the athletics facility Øya stadion and the Trondhjems Tennis Club (TTK) with four outdoor clay courts and indoor tennis hall.
