The disclosed computer-implemented method for utilizing information-asset metadata aggregated from multiple disparate data-management systems may include (1) receiving a request for information about one or more information assets of an entity whose metadata satisfies a metadata-search criterion, (2) identifying a global metadata repository that stores metadata of the information assets, (3) querying the global metadata repository for information about one or more of the information assets whose metadata satisfies the metadata-search criterion, (4) receiving, from the global metadata repository, information about at least one information asset whose metadata satisfies the metadata-search criterion, and (5) responding to the request using the information about the information asset. Various other methods, systems, and computer-readable media are also disclosed.
