Kava or kava-kava (Piper methysticum: Latin "pepper" + Latinized Greek "intoxicating") is a crop of the western Pacific.

The name kava(-kava) is from Tongan and Marquesan; other names for kava include ʻawa (Hawaiʻi),ʻava (Samoa),yaqona (Fiji),sakau (Pohnpei), and malok or malogu (parts of Vanuatu).

The roots of the plant are used to produce a drink with sedative, anesthetic, euphoriant, and entheogenic properties. Kava is consumed throughout the Pacific Ocean cultures of Polynesia, including Hawaii, Vanuatu, Melanesia and some parts of Micronesia for its sedating effects. Its active ingredients are called kavalactones. A Cochrane systematic review concluded it was likely to be more effective than placebo at treating short-term anxiety.

The several cultivars of kava vary in concentrations of primary and secondary psychoactive alkaloids. The largest number are grown in the Republic of Vanuatu, and so it is recognised as the "home" of kava. Kava was historically grown only in the Pacific islands of Hawaii, Federated States of Micronesia, Vanuatu, Fiji, the Samoas and Tonga. Some is grown in the Solomon Islands since World War II, but most is imported. Kava is a cash crop in Vanuatu and Fiji.
