Primulina is a genus of flowering plants in the African violet family Gesneriaceae. It includes 232 species native to southern and north-central China and northern Vietnam. The species are mostly calciphilous, and typically grow in the extensive limestone karst regions of China and Vietnam.
In 2011 the genus was expanded with the transfer of many species that had previously been placed in the genus Chirita. In 2016 five species were moved to the genus Deinostigma, which was merged into Metapetrocosmea in 2022. A phylogenetic study published in 2023 concluded that the southernmost three species of Primulina, endemic to the Langbiang Plateau in southern Vietnam, constitute a separate genus which was named Langbiangia.
