大角鹿属（Megaloceros）是生存于上新世晚期至更新世晚期欧亚大陆的鹿类，是冰河时期重要的草食性动物。其下最大的物种，正是最著名的大角鹿。

大角鹿属的大部份成员都是极大的动物，肩高接近2米，喜欢生活在草坪或林地。很多地中海物种都出现了侏儒化，例如M. cazioti就只有接近1米高。克里特的Candiacervus（有时被认为是大角鹿属的亚属）中，最细小的C. rhopalophorus肩高就只有65厘米。

大角鹿又名爱尔兰麋鹿，可见牠的习性可能像现今的马鹿，如加拿大马鹿或麋鹿。这有可能是因牠们体型上增加的后果。大角鹿属是于新近纪晚期从黇鹿演化而来，但现今黇鹿属本身就只余下两个物种。

Megaloceros (from Greek: μεγαλος, megalos + κερας, keras, literally "Great Horn"; see also Lister [1987]) is an extinct genus of deer whose members lived throughout Eurasia from the late Pliocene to the Late Pleistocene and were important herbivores during the Ice Ages. The largest species, Megaloceros giganteus, vernacularly known as the "Irish Elk" or "Giant elk", is also the best known.
