Brendan Cauldwell (25 October 1922 – 12 January 2006) was an Irish radio, film and television actor.
Cauldwell was born in Fairview, Dublin. He was educated at O'Connell's Irish Christian Brothers School and went on to work in the insurance industry before becoming a full-time actor. His interest in acting was encouraged by his uncle, who taught him different dialects in an attempt to solve a bad stammer.
In 1955, he joined the RTÉ Repertory Company. While with the company, he took part in more than 3,000 productions including the international 32-hour broadcast of Ulysses, the longest ever radio drama. In 1961, he performed in The Weaver's Grave. Adapted and produced by Mícheál Ó hAodha, it was written by Galway author Seamus O'Kelly, and won the Prix Italia for Radio Drama. He played another Joycean role when he acted as Father Michael in Joseph Strick's film, A Portrait of the Artist as a Young Man (1977).
His performance as Hennessy in the RTÉ Television production of Strumpet City is regarded as particularly memorable, alongside an earlier performance as Rashers Tierney in the RTÉ Radio 1 production.
Cauldwell died in his sleep in 2006, aged 83.
