Stemonoporus moonii (Sinhalese: Hora-wel) is a species of plant in the family Dipterocarpaceae. It is a shrub or small tree up to 4 metres tall which is endemic to southwestern Sri Lanka. It is known from a single location in Kalutara District, where it grows in the understorey of one of Sri Lanka's last remaining freshwater swamp forests and in marshy, periodically inundated areas near slow-running streams.[1] It is threatened by habitat loss from the conversion of swamp forests to rice fields. The IUCN Red List assesses the species as critically endangered.[1]

The species was first described by George Henry Kendrick Thwaites in 1858.[2]
