The Hungarian Ornithological and Nature Conservation Society (Hungarian: Magyar Madártani és Természetvédelmi Egyesület) (MME), also known as BirdLife Hungary, is a non-profit ornithological and nature conservation organisation founded in Hungary in 1974.

It has about 10,000 members, employs 26 staff, and is the Hungarian partner organisation of BirdLife International.

Initially it focussed on population surveys of threatened species, later expanding to promotion of, and lobbying for, nature conservation, as well as education and conservation fieldwork programs.

[4] Animals for which MME has been involved in conservation programs include the meadow viper, imperial eagle, saker falcon, great bustard, and white and black storks.

[1][2][4] Ornis Hungarica is a biannual peer-reviewed open access scientific journal covering ornithology published by the society.
