Charles Alexander Calvert (28 February 1828 – 12 June 1879) was a British actor and theatre manager known for arranging new productions of the Shakespearean canon featuring elaborate staging and what were considered historically accurate sets and costumes.

After leaving, he spent some time in the office of a London solicitor and in a mercer's business in St. Paul's Churchyard; but before long he was drawn to the stage, having derived a first impulse towards it from the plays of Shakespeare produced at Sadler's Wells Theatre by Samuel Phelps, from whom Calvert afterwards modestly declared that he had learnt all his art.

Five years later in 1864, by then manager of the newly built Prince's Theatre, Calvert began the series of Shakespearean "revivals" which were the chief efforts of his professional life.

Convinced that Shakespeare could be "made to pay," he consistently produced plays with elaborate attention to scenery, costume, and every other element of stage effect.

The Prince's Theatre passed into the hands of a company in 1868 who quickly rebuilt it, allowing Calvert to fulfill his promise of providing "dramatic entertainment of the highest class".
