Elections to the Seanad, the Senate of the Oireachtas (parliament of the Irish Free State), took place on a triennial basis, with senators elected in stages.

There were a total of 60 seats in the Free State Seanad.

However, at the 1928 and subsequent Free State Seanad elections, the franchise was restricted to Oireachtas members.

In 1922, 30 Senators had been elected by Dáil Éireann, and 30 had been nominated by the President of the Executive Council, W. T.
