James Tunney (1892 – 11 May 1964) was an Irish Labour Party politician who served for seven terms in Seanad Éireann and for one brief term in Dáil Éireann.
Elected to the 2nd Seanad by the Labour Panel in 1938, he was re-elected that year to the 3rd Seanad. In the 1943 general election, he was elected to the 11th Dáil for Dublin County, but lost his seat in the 1944 general election.
In the same year, Tunney was returned to the 5th Seanad by the Labour Panel. In 1948 he was elected to the 6th Seanad by the Agricultural Panel, which also elected him to the 7th Seanad in 1951. In 1954, he was nominated to the 8th Seanad by the Taoiseach, John A. Costello. In 1957, following the defeat of the second inter-party government, he was elected to the Seanad for a seventh and final time, again by the Agricultural Panel.
Tunney did not contest the 1961 election for the 10th Seanad.
