Paddy Glackin (born 5 August, 1954) is an Irish fiddler from Clontarf, Dublin. His father Tom Glackin was from Donegal and Paddy's fiddle style reflects his family's Donegal roots. Glackin is considered one of the leading Irish fiddlers in the late 20th/early 21st centuries. He became fiddle champion at the All-Ireland Fleadh Cheoil in 1973. Glackin's primary influence came from Donegal fiddlers, most prominently John Doherty the legendary travelling fiddler whom Glackin always cites as his main influence. His influences are not limited to Donegal however, he also cites fiddlers such as John Kelly, Tommy Potts and Padraig O'Keeffe as important in shaping his overall approach.
Paddy was an original member of Bothy Band when they were named Seachtar. The original line-up included Irish music legends Matt Molloy, Dónal Lunny, Paddy Keenan, Tony MacMahon, Tríona Ní Dhomhnaill and Mícheál Ó Domhnaill. When the group decided to become professional Paddy left and eventually became sports editor for RTÉ radio, Ireland's national broadcaster.
