Bernard Commons (15 May 1913 – 19 April 1965) was an Irish politician. A farmer by profession, he was an unsuccessful candidate at the 1943 and 1944 general elections. He was elected to Dáil Éireann at the Mayo South by-election on 4 December 1945 as a Clann na Talmhan Teachta Dála (TD) for the Mayo South constituency. The by-election was caused by the appointment of Micheál Clery of Fianna Fáil as County Registrar of Dublin. In the early 1940s, Commons was imprisoned for one month in Sligo Prison for his part in the Mayo land agitation, after which he won a Dáil seat.
