Reginald Horace Cumner (31 March 1918 – 18 January 1999) was a Wales international footballer. A forward, he played for Arsenal, Margate, Hull City, Notts County, Scunthorpe United, Bradford City, Poole Town, and Bridport. He won three international caps in the 1939 British Home Championship, scoring one goal.
Cumner moved from Aberaman Athletic to Arsenal. He was loaned out to Margate and Hull City. During World War II he guested for Cardiff City, Fulham, Liverpool, Portsmouth, Swansea Town, Aberaman Athletic, Port Vale, Clapton Orient and Plymouth Argyle. In August 1946, he signed for Notts County in part-exchange for Ian McPherson. He helped the "Magpies" to 12th and sixth place in the Third Division South in 1946–47 and 1947–48. He left Meadow Lane, and switched to league rivals Watford. He helped Eddie Hapgood's "Hornets" to finish 17th in 1948–49 and sixth in 1949–50. After departing Vicarage Road, he joined Leslie Jones's Scunthorpe United. He helped the "Iron" to mid-table finishes in the Third Division North in 1950–51, 1951–52, and 1952–53. He never played another game in the Football League after leaving the Old Showground, as he was signed to Ivor Powell's Bradford City, but never got onto the pitch at Valley Parade. He later moved into non-league football with Poole Town (Western League), Bridport (Dorset Combination), and Swanage Town.
