Irving was born to a working-class family in Keinton Mandeville in the county of Somerset.
W.H. Davies, the celebrated poet, was a cousin.
Irving spent his childhood living with his aunt, Mrs Penberthy, at Halsetown in Cornwall.
He competed in a recitation contest at a local Methodist chapel where he was beaten by William Curnow, later the editor of The Sydney Morning Herald.
He attended City Commercial School for two years before going to work in the office of a law firm at age 13.
When he saw Samuel Phelps play Hamlet soon after this, he sought lessons, letters of introduction, and work in a theatre in Sunderland in 1856, labouring against great odds until his 1871 success in The Bells in London set him apart from all the rest.

He married Florence O'Callaghan on 15 July 1869 at St. Marylebone, London, but his personal life took second place to his professional life.
On opening night of The Bells, 25 November 1871, Florence, who was pregnant with their second child, criticised his profession: "Are you going on making a fool of yourself like this all your life?"
Irving exited their carriage at Hyde Park Corner, walked off into the night, and chose never to see her again.
 He maintained a discreet distance from his children as well, but became closer to them as they grew older.
Florence Irving never divorced Irving, and once he had been knighted she styled herself "Lady Irving"; Irving never remarried.

His elder son, Harry Brodribb Irving (1870–1919), usually known as "H B Irving", became a famous actor and later a theatre manager.
His younger son, Laurence Irving (1871–1914), became a dramatist and later drowned, with his wife Mabel Hackney, in the sinking of the Empress of Ireland.
H B married Dorothea Baird and they had a son, Laurence Irving (1897–1988), who became a well-known Hollywood art director and his grandfather's biographer.

In November 1882 Irving became a Freemason, being initiated into the prestigious Jerusalem Lodge No 197 in London.
In 1887 he became a founder member and first Treasurer of the Savage Club Lodge No 2190, a Lodge associated with London's Savage Club.

He eventually took over the management of the Lyceum Theatre and brought actress Ellen Terry into partnership with him as Ophelia to his Hamlet, Lady Macbeth to his Macbeth, Portia to his Shylock, Beatrice to his Benedick, etc.
Before joining the Lyceum, Terry had fled her first marriage and conceived two out-of-wedlock children with architect-designer Edward William Godwin, but regardless of how much and how often her behavior defied the strict morality expected by her Victorian audiences, she somehow remained popular.
 It could be said that Irving found his family in his professional company, which included his ardent supporter and manager Bram Stoker and Terry's two illegitimate children, Teddy and Edy.

Whether Irving's long, spectacularly successful relationship with leading lady Ellen Terry was romantic as well as professional has been the subject of much historical speculation.
 Most of their correspondence was lost or burned by her descendants.
 According to Michael Holroyd's book about Irving and Terry, A Strange Eventful History:
Years later, when Irving was dead, Marguerite Steen asked Ellen whether she really had been Irving's lover, and she promptly answered: 'Of course I was.
 We were terribly in love for a while.'
But at earlier periods in her life, when there were more people around to be offended, she said contradictory things.

Terry's son Teddy, later known as Edward Gordon Craig, spent much of his childhood (from 1879, when he was 8, until 1897) indulged by Irving backstage at the Lyceum.
Craig, who came to be regarded as something of a visionary for the theatre of the future, wrote an especially vivid, book-length tribute to Irving.
 ("Let me state at once, in clearest unmistakable terms, that I have never known of, or seen, or heard, a greater actor than was Irving.")
George Bernard Shaw, at the time a theatre critic who was jealous of Irving's connection to Ellen Terry (whom Shaw himself wanted in his own plays), conceded
