裂谷热（英语：Rift Valley fever）又称作里夫谷热，是一种由病毒引起的人畜共通病，它的症状程度从轻微到严重都有。轻微的症状包括：发烧、肌肉疼痛、以及头痛（常持续数天到一周）；严重的症状则有：失明（通常在感染三周后发生）、脑部感染引起剧烈的头痛与神智混乱、以及伴随肝功能异常的出血（可能在最初几天出现）。有出血症状的患者的死亡率高达50%。

裂谷热起因于裂谷热病毒，属于白蛉热病毒属。此疾病借由接触染病动物的血液（在屠宰染病动物的现场可能吸入带有血液的空气而染病）、生乳、或是受到已感染蚊子的叮咬而传播。牛、绵羊、山羊与骆驼等动物也会被裂谷热感染，最常见的病媒为蚊子（通常为黑斑蚊属）。目前尚无发现人传人的病例。诊断方面，可借由寻找血液中病毒或病毒所产生的抗体而确诊。
