'''''Prockia''''' is a genus of flowering plants in the family Salicaceae. It consists of approximately six species of shrubs and small trees native to the West Indies, Mexico, Central America, and South America. Its type species, ''Prockia crucis'', is highly polymorphic and has a broad distribution, from Mexico and the West Indies to Uruguay and northern Argentina.

The genus name of ''Prockia'' is in honour of Christian Leberecht von Prøck (1718–1780), a Danish baron. He served as Governor-General of the Danish West Indies colonies from 1756 to 1766.<ref>{{cite book | last=Burkhardt | first=Lotte | title=Verzeichnis eponymischer Pflanzennamen – Erweiterte Edition |trans-title=Index of Eponymic Plant Names – Extended Edition | publisher=Botanic Garden and Botanical Museum, Freie Universität Berlin | year=2018 | isbn=978-3-946292-26-5 | url=https://doi.org/10.3372/epolist2018 |format=pdf |language=German |location=Berlin | doi=10.3372/epolist2018 |access-date=1 January 2021}}</ref> It was first described and published in Syst.

Historically, ''Prockia'' was characterized by having pseudo-axile placentation (i.e., parietal placentae that intrude into the center of the ovary and eventually fuse, appearing axile) and 3-merous flowers and lacking nectaries.<ref name="Sleumer">Sleumer, H.O. 1980. Flacourtiaceae. ''Flora Neotropica'' 22: 1-499.</ref> However, discoveries of new species have confounded a simple morphological diagnosis of the genus, as ''P. pentamera'' has 5-merous flowers, and ''P. oaxacana'' and ''P. krusei'' are polygamodioecious or androdioecious and have more typical parietal placentation.<ref>{{cite journal |last1=Jiménez Ramírez |first1=Jaime |last2=Cruz Durán |first2=Ramiro |last3=Vega Flores |first3=Karla |title=''Prockia oaxacana'' (Salicaceae), una especie nueva del Estado de Oaxaca, México |journal=Novon |date=2008 |volume=18 |issue=3 |pages=351–356 |doi=10.3417/2005037}}</ref> Formerly placed in the heterogeneous family Flacourtiaceae,<ref name="Lemke">Lemke, D.E. 1988.

''Prockia crucis'' is sometimes confused with ''Pineda ovata'' (Salicaceae) in the high elevations of Bolivia.<ref name="Alford">Alford, M.H. 2006. A taxonomic revision of the Andean genus ''Pineda'' (Salicaceae). ''Kew Bulletin'' 61: 205-214.</ref>
