Hal Roach (4 November 1927 – 28 February 2012) was a prominent Irish comedian. He spent over 60 years in show business as a live performer, having also recorded albums, DVDs and was featured in the Guinness World Records for the longest-running engagement of a comedian at the same venue: 26 years at Jury's Irish Cabaret, Jury's Ballsbridge Hotel, Dublin.

Born John Roche in Waterford, where he attended the Manor Christian Brothers school, Roche began his career after winning a local talent competition as a boy soprano. He initially toured with an illusionist and specialised in magic, but later moved to comedy.

Roach has been cited as a major influence by other comedians such as Brendan Grace.[2]

Roach was popular particularly with American tourists visiting Ireland. His act played heavily on traditional tourist imagery of Ireland and on Irish jokes. Several of his shows have been released on cassette and CD, and they are popular with tour bus drivers in several English-speaking countries who play them to passengers to help pass the time between destinations.

After suffering from a long bout of ill health, Roach died on 28 February 2012. The following month, RTÉ broadcast a tribute to Roach in one of its graveyard slots, a repeat airing of a programme from the That's Entertainment series first broadcast in 1972.
