539 Pamina is a minor planet orbiting the Sun in the main belt. It is named for the heroine of Mozart's opera, The Magic Flute. This asteroid was discovered by M. Wolf in 1904 at the Heidelberg observatory in Germany. It is orbiting at a distance of 2.74 AU from the Sun, with an orbital eccentricity (ovalness) of 0.212 and a period of 4.53 yr. The orbital plane is inclined at an angle of 6.8° to the ecliptic.

Photometric observations of this asteroid taken in 2004 provided a light curve showing a rotation period of 13.903±0.001 h with a brightness amplitude of 0.10±0.01 in magnitude. Infrared measurements give a diameter estimate of 54±3 km.
