Seán French (29 May 1890 – 12 September 1937) was a Fianna Fáil politician from Cork in Ireland. He was a Teachta Dála (TD) from 1927 to 1932.
A merchant and harbour commissioner, French stood unsuccessfully as an anti-Treaty Sinn Féin candidate for Dáil Éireann at a by-election in 1924 for the Cork Borough constituency. When Sinn Féin split in 1926 over the policy of abstentionism, he joined the breakaway Fianna Fáil party, and won the seat at the June 1927 general election — although like other Fianna Fáil TDs, he did not take his seat until 12 August 1927. He was re-elected at the September 1927 election, but did not contest the 1932 general election. He stood one more time, at the 1933 election, but did not regain his seat.
French was Lord Mayor of Cork from 1924 to 1929 and again from 1932 until his death in 1937. His son, also called Seán followed him into politics and served as both Lord Mayor and TD in Cork.
