"Encelia" is a genus of the plant family Asteraceae. It consists of shrubs (and one geophyte) of arid environments in southwestern North America and western South America. All have n = 18 chromosomes. With the exception of the South American species, all are obligate outcrossers. In cultivation, the species readily form fertile F1 hybrids, F2s, and backcrosses, but in natural areas of sympatry, F2s and backcrosses are absent or rare.

"Encelia" species are used as food plants by the larvae of some Lepidoptera species including the leaf-miner "Bucculatrix enceliae" which feeds exclusively on "Encelia farinosa".

The phylogenetic sister group of "Encelia" is a clade comprising the genera "Enceliopsis" and "Geraea". The three genera are informally called the "Encelia alliance".
