Thomas V. Honan (1878 – 21 October 1954), known as T. V. Honan, was a Fianna Fail politician in Ireland who served as a senator for 20 years.
He was elected in 1934 to Seanad Eireann, for the standard nine-year term which applied under the Constitution of the Irish Free State, but his term was cut short when the Free State Seanad was abolished in May 1936. However, the Seanad was re-established under the new Constitution of Ireland which was adopted in 1937, he was nominated by the Taoiseach in 1938 to the 2nd Seanad, and remained in the Senate until he stood down at the 1954 election. For the 6th Seanad from 1948–51, he was elected by the Industrial and Commercial Panel.
His son Dermot was a senator from 1965 to 1973, and Dermot's widow Tras was a senator from 1977 to 1982. She was twice elected as Cathaoirleach (speaker).
