Directories of Romanian organizations and officials can be used by genealogists to find information about people from the years before the rise of telephone books, or when telephones were not yet commonly available. Such directories can also be used by historians studying a certain era or region.

Like the other types of directories also listed in this guide, such as telephone books and particularly yellow pages, the information in these directories is organized either by city or county, or by type of organization and type of services.

The list below is organized alphabetically by title.
