Tibouchina is a neotropical flowering plant genus in Melastomataceae Juss. That contains approximately 240 species. Species of this genus are herbs, shrubs or trees and typically have purple flowers. They are native to Mexico, the Caribbean, and South America, where they are found as far south as northern Argentina. Members of this genus are known as glory bushes, glory trees or princess flowers. The name Tibouchina is adapted from a Guianan indigenous name for a member of this genus. A recent systematic study has shown that this genus is paraphyletic.

Members of Tibouchina sensu lato are diagnosed by a number of traits, including pentamerous flowers with anthers having developed pedoconnectives (the connective tissue below the anther locules) and another appendages that are ventrally bi-lobed. These traits are likely plesiomorphic in the core Melastomeae. The magenta or purple flowers are often showy, and the stamens may be dimorphic. Members of Tibouchina have simple leaves that lack stipules with the conspicuous ladder-like venation that is characteristic of most melastomes. As a member of Melastomeae, Tibouchina also has capsular fruit and cochleate seeds.

Several species are cultivated for their large, bright flowers. As tropical plants, they are rather cold-sensitive, and should be raised in a greenhouse wherever temperatures fall below 8 °C to 10 °C. One species, Tibouchina lepidota ('Alstonville'), known for its brilliant display of flowers in late summer and autumn, is common in many parts of Australia. In Australia, both this species and Tibouchina grandiflora and cultivars are commonly known as Lasiandra. They are closely related to a native shrub Melastoma affine also known as Native Lasiandra. All these plants are featured and celebrated in the annual Lasiandra Festival held in the small country town of Wauchope, which is situated in the hinterland of the Central New South Wales Coast, City of Port Macquarie. Bright purple, the colour of the flowers, forms the central theme of the festival.
