Dessie O'Halloran (born 29 August 1940) is an Irish singer and musician.
A native of Inishbofin, County Galway, O'Halloran emigrated to the UK in the 1950s, where he enjoyed regular success as a singer at the All-Britain championships. Returning to Inishbofin in the mid-1980s, O'Halloran joined the island’s céilí band, with whom many visiting musicians would sit in, as well as playing at sessions on the island.
He gained chart success in 2001 with Say You Love Me, which reached No. 4 on the Irish charts, and was later re-released as a remix. The song was taken from the Sharon Shannon album, The Diamond Mountain Sessions.
His 70th birthday party, held in Fagan's Bar, Hotel Meyrick, Eyre Square, Galway, on August 29, 2010, was attended by musicians such as Sharon_Shannon, Joe Burke, Anne Conroy Burke, Frankie Gavin, Matt Keane, Mary Staunton, Tommy McCarthy, Mick Crehan, Gerry Hanley, Rosie Stewart and Dick Hogan. Also in attendance were jockeys Ruby Walsh, Barry Geraghty and David Casey, as well as politicians Frank Fahey and former Mayor of Galway Pádraig Conneely.
O'Halloran still performs, either with Sharon_Shannon's Big Band or the Fuaim Chonamara show by the Cuningham dancing family.
