L'earth-moon-earth (EME) (terre-lune-terre) est une discipline de télécommunication radioamateur fondée sur la propagation d'ondes radios par réflexion sur la Lune.

Les bandes radios employées sont la VHF et l'UHF, et la puissance rayonnée doit être supérieure à 500 W. Ceci est dû à la faible valeur de l'albedo lunaire (environ 12 %) et à l'importance de la distance entre la Terre et la Lune (en moyenne 384 400 km, l'affaiblissement de propagation (« Path-loss ») est donc très important).
