See text Agavoideae is a subfamily of monocot flowering plants in the family Asparagaceae, order Asparagales.

About 640 species are placed in around 23 genera;[2] they are widespread in the tropical, subtropical, and warm temperate regions of the world.

In general, Agavoideae leaves occur as rosettes at the end of a woody stem, which may range from extremely short to tree-like heights, as in the Joshua tree.

Agave species are used to make tequila, pulque, and mezcal, while others are valued for their fibers.

In the APG III system of 2009, adopted here, the Agavoideae are defined very broadly to include the former family Agavaceae along with other formerly separate families such as Anemarrhenaceae, Chlorogalaceae, Hostaceae, Yuccaceae, Anthericaceae, Hesperocallidaceae, and Chlorogalaceae, based on data from molecular systematics.
