A wreath decoration mounting system is a system that enables the mounting, positioning, and orienting of different ornaments around a wreath's center. The system can be attached at various locations and angles along the wreath's wire frame to support the different ornaments that would otherwise be glued or wired to the wreath's wire frame. The system may include a first wire fastener, a second wire fastener, a support beam, and a support platform. The first wire fastener and the second wire fastener secure the support beam to the wreath's wire frame. The first wire fastener and the second wire fastener also help offset the support beam from the wire frame to hide the support beam behind the wreath. The support beam receives the load from the support platform and any ornament mounted onto the support platform. The support platform facilitates the mounting of the desired ornaments to the support beam.
