The Muroidea are a large superfamily of rodents, including mice, rats, voles, hamsters, lemmings, gerbils, and many other relatives. Although the Muroidea originated in Eurasia, [1] they occupy a vast variety of habitats on every continent except Antarctica.

鼠，又稱老鼠，即鼠總科（Muroidea），是一種屬於囓齒類的總科，其中含有倉鼠、沙鼠、大鼠，以及其他親緣動物。 牠們廣泛分佈於 南極 以外的各個 大陸 。

鼠科是哺乳动物中最大的科。鼠科动物的臼齿缺少纵列的釉质齿突，这是区别于仓鼠科的特征。分子证据也支持将鼠科从鼠总科 Muroidea的姊妹分类单元仓鼠科 Cricetidae中分离出来，二者分化时间大约在2400万年前。

鼠总科的分类又不同意见，有人将其分成主要分布于新大陆和北方大陆的 仓鼠科 Circetidae，分布于旧大陆的 鼠科 Muridae，分布于旧大陆荒漠地区的 沙鼠科 Gerbillidae和旧大陆的穴居类型 瞎鼠科 Spalacidae和 竹鼠科 Rhizomyidae，仓鼠科常被并入鼠科，有时沙鼠科甚至所有的鼠总科都并 …

Muroidea is a large superfamily of rodents. It includes hamsters, gerbils, true mice and rats, and many other relatives. They live on almost every continent except Antarctica. Some scientists have placed all members of this group into a single family, Muridae.

The superfamily Muroidea includes most of the familiar rats and mice, but it also encompasses an enormously diverse array of other rodents. Currently there are 1517 recognized species and 310 genera of muroid rodents.
