Harper Oliver Hamshaw (birth registered fourth ¼ 1863 – death registered first ¼ 1925) was an English rugby union footballer who played in the 1880s. He played at representative level for Yorkshire, and at club level for Wakefield Trinity (it was a rugby union club at the time, so no Heritage № has been allocated). Prior to Tuesday 27 August 1895, Wakefield Trinity was a rugby union club. A rugby shirt worn by Harper Hamshaw is on display at Wakefield Museum, and was used as the inspiration for a heritage shirt produced in 2010.
