Gudrun (minor planet designation: 328 Gudrun) is a main-belt asteroid.

It was discovered by Max Wolf on March 18, 1892, in Heidelberg.

Analysis of the light curve generated from photometric data collected in March 2012 provide a rotation period estimate of 10.992±0.002 h with a brightness variation of 0.32±0.02 in B magnitude.[4]
