Petrache Poenaru, formerly known as Semănătoarea is a metro station in Bucharest, Romania, servicing the Bucharest Metro Line M1. It was named after Semănătoarea, an agricultural machinery factory located in the vicinity, but it is now named after Petrache Poenaru, a Romanian inventor of the Enlightenment era. The metro station services both what is left of the factory, part of the Regie student campus, the Sema Park industrial park, as well as some newly built residential areas. It is also located close to the Semănătoarea (Ciurel) Metro Depot.
