Hugo Victor Flinn (1880 – 28 January 1943) was an Irish Fianna Fáil politician.
Hugo Flinn was born in Kinsale, County Cork in 1880. He was educated locally in Cork before his family moved to England where Hugo qualified as an electrical engineer and worked with the Liverpool Electricity Supply Board. He returned to Cork in the 1920s and set up a radio business.
Flinn was recruited into the Fianna Fáil party upon his return to Ireland and won a seat in the 6th Dáil at the September 1927 general election in Cork Borough. He retained his seat at each subsequent election until his death in 1943. After Fianna Fáil's election victory in 1932 Flinn was appointed as Parliamentary Secretary to the Minister for Finance Seán MacEntee. He remained in this department until 1939 when he also became Parliamentary Secretary to the Minister for Local Government.
Flinn became Fuel Controller during World War II and was a strong supporter of Todd Andrews and the Turf Development Board, which later became Bord na Móna. Hugo was widely considered an able and articulate Parliamentary Secretary and it is said that he was denied Ministerial office as he had no background in either the War of Independence and the Civil War. Up until his death he was conducting a lively discussion in the Irish Independent letters pages advocating the abolition of income tax.
