Reginald Flewin (28 November 1920 – 24 May 2008) was an English footballer who played as a central defender for his hometown club Portsmouth.
Reg Flewin was spotted playing in the Hampshire League for Ryde Sports. He signed a professional contract with Portsmouth on his 17th birthday in 1937, and made his senior debut for the club against Grimsby Town in April 1939. Following the outbreak of World War II, Flewin's football career came to a halt. He served in the Royal Marines during hostilities, and occasionally turned out for Portsmouth in wartime football, winning an England wartime cap against Wales on 16 September 1944.[1]
When football resumed at the end of the war, Flewin became a regular in Portsmouth's defence, and was also named the team's captain. He was a member of the sides that won consecutive league titles in 1948–49 and 1949–50. In 1949 the team was tipped to become the first to win the double but lost to Leicester City. Flewin retired in 1953, having played 163 first-team matches for Portsmouth.
Following his playing career, Flewin moved into coaching. He first took charge of Portsmouth's youth team, and later became assistant to manager Eddie Lever. He remained assistant manager at Portsmouth until October 1960, when he accepted the job as manager of Stockport County. In September 1963, he moved back south to become manager at Bournemouth, where he spent two years before resigning in 1965.
After leaving football, Flewin settled on the Isle of Wight, where he managed the Fort Warden holiday camp in Totland Bay. He died in May 2008, aged 87 a week after the 2008 FA Cup Final.
