975 Perseverantia is a minor planet orbiting the Sun that was discovered by Austrian astronomer Johann Palisa on 27 March 1922.

This is a member of the dynamic Koronis family of asteroids that most likely formed as the result of a collisional breakup of a parent body;[2] the semi-major axis of the orbit of 975 Perseverantia lies just outside the 5/2 Kirkwood gap, located at 2.824 AU.[3]
