Timothy J. ("T.J.") Murphy (died 29 April 1949) was a senior Irish Labour Party politician.
A native of Dunmanway, he was first elected to Dáil Éireann at the 1923 general election as a TD for Cork West. He was re-elected at the next nine general elections, but remained on the opposition benches of the Dáil until 1948 when the Labour Party joined the First Inter-Party Government. The Taoiseach John A. Costello then appointed him as Minister for Local Government.
Murphy died suddenly in 1949, little more than a year into his tenure as a Cabinet Minister. The by-election for his seat in the Dáil was held on 15 June 1949, and won for the Labour Party by William J. Murphy.
His brief time as minister had seen him initiate a comprehensive house-building programme, designed to tackle the country's considerable housing shortage. By 1951, some 12,000 new houses had been constructed.
An area of Murphy's home town of Dunmanway today bears the name "T.J. Murphy Place".
