قاعدة بيانات ليون-ميودون فوق المجرية (بالإنجليزية: Lyon-Meudon Extragalactic Database) وتُدعى اختصاراً LEDA هي قاعدة بيانات للمجرات، أنشئت في عام 1983 في مرصد ليون. وكان لكل مجرة رقم مخصص، يعرف برقم PGC . فهرس المجرات الرئيسية الذي نشر في عام 1989، يستند إلى قاعدة بيانات ليون-ميودون .

The Lyon-Meudon Extragalactic Database (LEDA) was a database of galaxies, created in 1983 at the Lyon Observatory. Each galaxy had a number assigned to it, which is now known as its PGC number. The Principal Galaxies Catalogue (PGC), published in 1989, was based on the Lyon-Meudon Extragalactic Database and contained cross-identifications for it. LEDA was eventually merged with to become HyperLEDA in 2000, itself also known as PGC2003. LEDA originally contained information on more than 60 parameters for about 100,000 galaxies, and now contains information on over 3 million celestial objects, of which about 1.5 million are galaxies. The database allows astronomers around the world access to its information.

Originariamente conteneva informazioni su oltre 60 parametri di circa 100.000 galassie. In seguito a continui aggiornamenti ed ampliamenti, oggi contiene informazioni su oltre tre milioni di oggetti celesti, dei quali 1,5 milioni sono galassie. L'accesso alle informazioni contenute nel database è consentito agli astronomi di tutto il mondo.

La Lyon-Meudon Extragalactic Database (LEDA) est une base de données et un ensemble d'outils destinés à l'étude des galaxies et de la cosmologie. Ce projet a débuté en 1983 et il est le résultat d'une collaboration entre l'observatoire de Lyon en France et l'observatoire spécial d'astrophysique en Russie. En 2017, la base de données renfermait plus de cinq millions d'objets.Le LEDA est devenu le HyperLEDA au cours de l’année 2000 après avoir fusionné avec le HyperCAT.

Den innehöll ursprungligen information om mer än 60 parametrar för cirka 100 000 galaxer, och nu innehåller den uppgifter om över 3 miljoner himlakroppar, varav cirka 1 500 000 är galaxer. Databasen ger astronomer världen över tillgång till sin information.
