Eamonn O'Neill (died 3 November 1954) was an Irish Cumann na nGaedheal and later Fine Gael party politician, and TD for the Cork West constituency.
O'Neill was an unsuccessful Cumann na nGaedheal candidate at the September 1927 general election in the 5-seat Cork West constituency. He stood again at the next opportunity, at the 1932 general election, and was elected to the 7th Dáil Éireann. He was re-elected at the next three general elections, before losing his seat at the 1943 general election to the Clann na Talmhan candidate Patrick O'Driscoll.
He was re-elected a year later, at the 1944 general election, unseating his Fine Gael colleague Timothy O'Donovan.
The constituency was reduced to a 3-seater at the 1948 general election, and O'Neill was not re-elected. He did not contest any further elections.
