58 Concordia is a fairly large asteroid-belt asteroid. It is classified as a C-type asteroid, meaning that its surface is very dark and it is likely carbonaceous in composition.

Concordia was discovered by Robert Luther on March 24, 1860. At Luther's request, it was named by Carl Christian Bruhns of the University of Leipzig after Concordia, the Roman goddess of harmony.[2]
