Liam Naughten (30 May 1944 – 16 November 1996) was an Irish Fine Gael politician, who was a Teachta Dála (TD) for the constituency of Roscommon from 1982 to 1989, and also served as a Senator.
A farmer, he first contested the 1977 general election in Roscommon-Leitrim but was not elected. He was again unsuccessful in the 1981 election but was elected to the 15th Seanad on the Agricultural Panel.
He was finally elected to Dáil Éireann in 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.
In 1995 when Fine Gael formed a Government Naughten became Cathaoirleach of the Seanad.
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.
