A farmer, he first contested the 1977 general election for the Roscommon–Leitrim constituency but he was not elected. He was again unsuccessful at the 1981 general election but was elected to the 15th Seanad on the Agricultural Panel.
He was finally elected to Dáil Éireann at the February 1982 general election for the Roscommon constituency and held his seat until losing it at the 1989 general election to Fine Gael running-mate John Connor. He was again elected to the Seanad and retained this seat after again failing to be elected for Longford–Roscommon at the 1992 general election.
Liam Naughten died in a traffic accident in November 1996. His son Denis Naughten, aged 24, was elected in a by-election to fill his Seanad seat and was elected to the Dáil in the 1997 general election.
