'''''Monanthes''''' is a genus of small, succulent, subtropical plants of the family Crassulaceae. Most species in the genus are endemic to the Canary Islands, with one species also endemic to the Savage Islands and another to the High Atlas mountains of Morocco. Its center of diversity is Tenerife, with seven species occurring on this island. On Fuerteventura and Lanzarote, only ''M. laxiflora'' occurs. ''Monanthes'' is a rare example where a species re-colonizes the continent from an island, after their ancestors have colonized the island from the continent.{{citation needed|date=May 2009}}
''Monanthes'' are not frost-resistant. They are linked with the genera ''Sempervivum'', ''Greenovia'', ''Aichryson'' and ''Aeonium'', which is obvious from their similar flowers.
Species of ''Monanthes'' differ considerably in life- and growth-form. ''M. icterica'', which is also genetically quite distant to other ''Monanthes'' species, is annual, while the other species are perennial.
