A pet tag holder supports from a pet collar a pet tag having a hole. The pet tag holder comprises a flexible, resilient body including a major front wall, an opposed major rear wall, side edge walls interconnecting the front and rear walls, a top edge wall, and a bottom edge wall. The top and bottom edge walls are continuous with the side edge walls and interconnect the front and rear walls. The body defines a hollow sleeve having an interior cavity adapted for receiving and enclosing at least one pet tag and a slot for inserting the tag into the sleeve.
