Frank Chambers (born 3 March 1949) is an Irish Fianna Fáil politician from Newport, County Mayo.
Married with four children, Chambers is an auctioneer and farmer. His daughter Lisa was involved in establishing Renua Ireland in 2015; she is not to be confused with Fianna Fáil TD Lisa Chambers, who is not related to them.
Chambers was a member of Mayo County Council from 1976. He was first elected in 1979 and stood down at the 2009 election.
At the 1997 election to Seanad Éireann he stood for election by the Cultural and Educational Panel, but was unsuccessful. After his defeat he was nominated by the Taoiseach, Bertie Ahern, to the 21st Seanad, but was not re-appointed in 2002. He stood in the Mayo constituency at the 2002 and 2007 general elections, but did not win a seat.
Chambers and fellow FF councillor Tim Quinn from Belmullet are the only Fianna Fáil politicians to back the Shell to Sea campaign.
