耳廓狐（学名：Vulpes zerda）也称耳郭狐、狐、大耳小狐、大耳狐与沙漠小狐，是一种分布于北非撒哈拉的小型夜行狐，以其不同寻常的大耳朵而闻名。其英文名Fennec来自于阿拉伯语狐狸一词；其种名zerda出自希腊语单词ξηρός（xērós），意为“干燥”，是对其栖息地的描述。耳廓狐是最小的犬科动物，其皮毛、耳和肾功能都适应了高温缺水的沙漠环境。另外其听力十分敏锐，足以感觉到地下猎物活动。

耳廓狐在野外可以存活大概10年，其主要天敌包括狞猫和非洲种的雕鸮。耳廓狐群会在沙中挖掘大约120平方米的洞穴以防护与居住，这些洞穴甚至会与其他耳廓狐群洞穴相连。目前无法精确测出耳廓狐种群数目，但由目击估计该物种尚未面临灭绝威胁。虽然常被分类为狐属，耳廓狐的分类尚有争议。北非原住民认为耳廓狐的皮毛是珍贵的，世界其他地方则认为耳廓狐是一种有异国情调的宠物。

The fennec fox or fennec (Vulpes zerda) is a small nocturnal fox found in the Sahara of North Africa. Its most distinctive feature is its unusually large ears, which also serve to dissipate heat. Its name comes from the Arabic word فنك (fanak), which means fox, and the species name zerda comes from the Greek word xeros which means dry, referring to the fox's habitat. The fennec is the smallest species of canid. Its coat, ears, and kidney functions have adapted to high-temperature, low-water, desert environments. In addition, its hearing is sensitive enough to hear prey moving underground. It mainly eats insects, small mammals, and birds.
