Capsella is a genus of herbaceous annual and biennial plants in the family Brassicaceae.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> It is a close relative of Arabidopsis, Neslia, and Halimolobos.<ref name="slotte" />

Some authors circumscribe Capsella to contain only three species: Capsella bursa-pastoris, Capsella rubella and Capsella grandiflora.<ref name="slotte">Template:Cite journal</ref> Template:As of, Kew's Plants of the World Online list eight species.Template:R

Capsella rubella is a self-fertilizing species that became self-compatible 50,000 to 100,000 years ago. Its outcrossing progenitor was Capsella grandiflora. In general, the shift from outcrossing to self-fertilization is among the most common transitions in flowering plants. Capsella rubella is studied as a model for understanding the evolution of self-fertilization.<ref name="pmid24068948">Template:Cite journal</ref><ref name="pmid23749190">Template:Cite journal</ref>

The name is said to derive from Latin capsa, a box or case, alluding to fruit resembling a medieval wallet or purse;<ref name="efloras">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> the suffix -ella denotes "lesser".<ref name="gledhill">Template:Cite book</ref>
