Eotitanops ('dawn titan-face') is an extinct genus of brontothere native to North America and Asia.

Eotitanops is the earliest known genus of brontothere. While brontotheres generally known as very large animals, Eotitanops was only 45 centimetres (1.48 ft) tall at the shoulder. It probably resembled a larger, bulkier version of its contemporary, the horse-like palaeothere Hyracotherium. Like Hyracotherium, it ate leaves and had five-toed front legs and three-toed hind legs.2
