Astrodatabank is a freely accessible wiki that compiles astrological data, primarily focusing on birth details and charts of public figures and significant events. Its origins trace back to 1979 when astrologer Lois Rodden began collecting and publishing such information, notably in her book "Profiles of Women." Over time, this collection evolved into the Astrodatabank, with contributions and development by individuals like Mark McDonough and Edwin Charles Steinbrecher. The project was later acquired by the Swiss company Astrodienst AG in 2008 and transformed into its current wiki format, launched in March 2009. The database is maintained in English and is recognized for its extensive collection of verified astrological charts, serving as a valuable resource for astrological research and studies.

The foundation of Astrodatabank was laid in 1979 by Lois Rodden, an astrologer who initiated the collection and publication of astrological birth data. This endeavor initially manifested in her book, "Profiles of Women," and subsequently grew into the comprehensive Astrodatabank. Mark McDonough played a significant role in developing the database structure, organizing the vast amount of data Rodden had gathered over four decades. Before her passing, Rodden designated Pat Taglilatelo as her successor. The database also incorporated the lifelong collection of Edwin Charles Steinbrecher. Ownership transitioned in 2005 to Richard Smoot, and in 2008, the Swiss company Astrodienst AG, owned by Alois Treindl, acquired Astrodatabank. Under Astrodienst, it was converted into a wiki, making the extensive data freely available to the public.

Astrodatabank is widely recommended for research within astrological studies. Organizations such as the National Council for Geocosmic Research and the Astrological Association of Great Britain have endorsed it as a substantial repository of verified astrological charts and a beneficial resource for scientific inquiry. Researchers have utilized the data, importing it into statistical software like SPSS for analysis, with some asserting that Astrodatabank sets high standards for astrological methodology and aligns with social scientific research design. Exported data has also been processed by open-source tools like TkAstroDb, developed by Tanberk Celalettin Kutlu, to perform statistical analyses of the included categories. The findings from some statistical analyses suggest that claimed astrological variations might be attributable to sampling errors rather than inherent astrological factors, with observed effects often being too small for individual-level prediction.

The data within Astrodatabank is meticulously recorded and rated, encompassing birth details of celebrities, public figures, and royal individuals, as well as dates of significant events. Entries are contributed by editors and data collectors and undergo a review process by a main editor to ensure reliability and notability before publication. A key feature is the Lois Rodden Rating system, which ranks entries based on the accuracy and source of the information. This system requires full citation of source notes. The highest ratings, such as 'A' and 'AA' (introduced at Marion March's suggestion to differentiate between birth certificates and personal memory), denote high accuracy. The lowest rating, 'DD' (dirty data), signifies unreliable, speculative, or contradictory information, often arising from third-rate sources or conflicting accounts.
