The Wanganui was an iron Brigantine Twin Boiler Screw steamer built by Gourlay Brothers & Co and launched in July 1863 for the Wanganui Steam Navigation Company for trade around the Wanganui region of New Zealand. The vessel served in this region up to 1873 when its ownership was transferred to Messrs Henry Houghton and Co., of Dunedin. In 1880 the vessel was transferred in to the Australian East coast service where it sank whilst entering Clarence River on 20 June 1880.
