恐象（学名：Deinotherium）是象的史前亲属，生存于中新世中期至更新世早期。在这段时间，恐象只有少许变化。恐象像现今的象，但鼻较短，而象牙则向下弯曲。

恐象是最大的长鼻目动物之一，也是已知陆上最大的哺乳动物之一，次于巨犀和副巨犀。雄性恐象一般肩高3-4.5米，最大的可达5米。估计体重超过12吨。恐象分布于亚洲、非洲及欧洲等地区。艾德丽安·梅约（Adrienne Mayor）指在希腊发现的恐象化石解开了古代巨大生物的秘密。 在克里特岛浅沉积岩中发现的恐象牙齿却令人质疑，究竟恐象是生活在大陆上，或是像现今的象般被人低估了其游泳的能力。

Deinotherium ("terrible beast" derived from the Ancient Greek δεινός, deinos meaning "terrible" and θηρίον, therion meaning "beast") was a large prehistoric relative of modern-day elephants that appeared in the Middle Miocene and survived until the Early Pleistocene. During that time it changed very little. In life, it probably resembled modern elephants, except that its trunk was shorter, and it had downward curving tusks attached to the lower jaw.
