舌蝇属（属名：Glossina，即采采蝇，来自英语：Tsetse 英语发音：/ˈsiːtsi/，US英语发音：/ˈtsiːtsi/， 或 UK英语发音：/ˈtsɛtsi/）是双翅目舌蝇科（Glossinidae）下唯一的一个属，其下的蝇广泛分布于从撒哈拉沙漠到喀拉哈里沙漠的广大非洲地区。 他们以吸食脊椎动物的血液为生，是非洲主要的睡病虫传播媒介之一。

因为会传播昏睡病而被广泛研究。这些蝇是多化性的，每年可繁殖四代，一生中最多可繁殖31代。 发现于科罗拉多州佛洛里森特化石层采采蝇的化石 证明其在3400万年前就生活在地球上了。

Tsetse (/ˈsiːtsi/, US /ˈtsiːtsi/, or UK /ˈtsɛtsi/), sometimes spelled tzetze and also known as tik-tik flies, are large biting flies that inhabit much of midcontinental Africa between the Sahara and the Kalahari Deserts. They live by feeding on the blood of vertebrate animals and are the primary African biological vectors of trypanosomes, which cause human sleeping sickness and animal trypanosomiasis, also known as nagana. Tsetse flies include all the species in the genus Glossina, which are generally placed in their own family, Glossinidae.
