Mimosa somnians, commonly known as dormideira, is a species of woody shrub in the genus Mimosa and the family Fabaceae. It is native to the Caribbean, Central America and South America. It is a short, low-lying shrub with minuscule thorns lining its stem-like hairs.

Mimosa somnians is notable for exhibiting rapid plant movement. Its leaves are sensitive to tactile stimulus, folding quickly when touched, similar to Mimosa pudica. It can be differentiated from Mimosa pudica in that its leaves are bipinnate, there are more than four subbranchlets and these originate from more than one point on the branch.

Mimosa somnians's leaflets are 4–5 mm long. The flowers form pink balls. It propagates by seeds.
