The Voice of Ireland series 4

The Voice of Ireland is an Irish reality talent show. The fourth series of the programme premiered on 4 January 2015 on RTÉ One and concluded on 26 April, similar to previous seasons. Kathryn Thomas returned as main host, while her colleague Eoghan McDermott remained the show's co-host. Television personalities Bressie and Kian Egan both returned as coaches, while The Saturdays singer Una Healy and S Club 7 star Rachel Stevens filled the remaining two positions. Screentime Shinawil Productions continued to produce the talent programme.

Patrick Donoghue was crowned the winner on 26 April 2015, with his version of Jessie J's Mama Knows Best, which was later released on iTunes. He was coached by The Saturdays singer Una Healy. After winning the recording contract with Universal, Donoghue decided to change his stage name to Patrick James as he found it represented him more as an artist.
