Рогу́льник, или Чили́м, или Водяно́й орех, или Водяной каштан, или Чёртов орех (лат. Trāpa) — род водных цветковых растений монотипного подсемейства Trapoideae семейства Дербенниковые (Lythraceae). Ранее этот род выделялся в самостоятельное семейство Рогульниковые, или Водяные орехи, или Водяноореховые (Trapaceae). Название «рогульник» связано с особенностями строения плодов, на зрелых костянках которых образуются твёрдые изогнутые выросты, формой напоминающие рога.
