Trichocentrum, often abbreviated Trctm in horticulture, is a genus in the orchid family, Orchidaceae. It was described by Stephan Ladislaus Endlicher and Eduard Friedrich Poeppig in 1836; the type species is the Long-spurred Trichocentrum (T. pulchrum). This genus alone makes up the monogeneric Trichocentrum alliance, a quite distinct lineage of the subtribe Oncidiinae
The 65 or so epiphytic species are distributed in damp forests from Mexico to South America, but mostly in Venezuela, Colombia, Ecuador and Peru as well as southern Central America.
