The machete ( /məˈʃɛti/; Spanish pronunciation: [maˈtʃete]) is a large cleaver-like cutting tool. The name is Spanish, meaning "little sledgehammer." The blade is typically 32.5 to 60 centimetres (12.8 to 24 in) long and usually under 3 millimetres (0.12 in) thick. In the English language, an equivalent term is matchet, though it is less commonly known. In the English-speaking Caribbean such as Jamaica, Guyana, Grenada and in Trinidad and Tobago, the term "cutlass" is used for these agricultural tools.

In various tropical and subtropical countries, the machete is frequently used to cut through rain forest undergrowth and for agricultural purposes (e.g. cutting sugar cane). Besides this, in Latin America a common use is for such household tasks as cutting large foodstuffs into pieces—much as a cleaver is used—or to perform crude cutting tasks such as making simple wooden handles for other tools. It is also common to see people using machetes for other jobs such as splitting open coconuts, working the lawns, and clearing brush. Because the machete is common in many tropical countries, it is often the weapon of choice for uprisings. For example the Boricua Popular Army are unofficially called Macheteros because of the machete-wielding laborers of sugar cane fields of past Puerto Rico.
