Harry Spencer Hamer (1863 — 21 December 1913) was the club secretary at Bury Football Club from 1888 until his death from pleurisy in 1913. From 1895 to 1907, the Bury team was managed by a three-man committee which may have included Hamer. The team were in the First Division throughout this period, their best position being fifth; and they won the FA Cup twice, in 1900 and 1903, with final victories of 4–0 and 6–0 respectively.
