九带犰狳（学名：Dasypus novemcinctus）是一种生活在北美洲、中美洲及南美洲的犰狳。牠们是最为广泛分布的一种。牠的祖先在南美洲演化，并在300万年前的南北美洲生物大迁徙进入北美洲。

九带犰狳是独行及主要夜间活动的动物，在很多地方都可以见到牠们，如雨林及草原。牠们是吃昆虫的，主要吃蚁、白蚁及其他细小的无脊椎动物。

九带犰狳可以令其肠脏膨涨，方便渡河。牠们亦可以闭气达6分钟，经底部穿过河流。每胎生产四只幼犰狳。九带犰狳若被惊吓，可以跳起达90-120厘米。

The nine-banded armadillo (Dasypus novemcinctus), or the nine-banded, long-nosed armadillo, is a medium-sized mammal found in North, Central, and South America, making it the most widespread of the armadillos. Its ancestors originated in South America, and remained there until the formation of the Isthmus of Panama allowed them to enter North America as part of the Great American Interchange. The nine-banded armadillo is a solitary, mainly nocturnal animal, found in many kinds of habitats, from mature and secondary rainforests to grassland and dry scrub. It is an insectivore, feeding chiefly on ants, termites, and other small invertebrates. The armadillo can jump 3–4 ft (91–122 cm) straight in the air if sufficiently frightened, making it a particular danger on roads. It is the state small mammal of Texas.
