**Kemiriciler** veya **Kemirgen** (Latince: Rodentia), yaşadıkları çevreye uyum bakımından çok başarılı olan bir memeli takımıdır.

Alt ve üst çenelerinde ikişer tane sürekli büyüme eğiliminde olan kesici dişler bulunur ve köpek dişleri yoktur. Gözler başın her iki yanında toplandığından hem önlerini hem arkalarını aynı derecede görebilirler. Çok iyi koşar, tırmanır, sıçrar ve yüzerler. Yılda birkaç kere ve her batında 1-18 yavru doğurabilirler.

Çoğu kemirici, sağlam gövdeli, kısa uzuvları ve uzun kuyrukları olan küçük hayvanlardır. Keskin kesici dişlerini yiyecekleri kemirmek, yuvaları kazmak ve kendilerini savunmak için kullanırlar. Genellikle tohum veya diğer bitki materyallerini yerler. Sosyal hayvanlardır ve birçok tür, birbirleriyle karmaşık iletişim yolları olan toplumlarda yaşar.
