Thomas Harris (died 1820) was an English theatre manager, who became proprietor of Covent Garden Theatre.
His background was in business. In the autumn of 1767, with George Colman the elder, John Rutherford, and William Powell, he purchased from John Beard the patent of Covent Garden Theatre. The theatre opened 14 September 1767, with The Rehearsal, in which Powell spoke a prologue by William Whitehead.
Colman took on a management role, but a serious quarrel broke outbetween Harris and Colman arose during the first season, driven by the ambitions of Jane Lessingham, an actress with whom Harris lived. Colman, with whom Powell sided, barricaded the theatre, and Harris, supported by Rutherford, broke it forcibly open. Legal proceedings and a pamphlet war followed. On 23 July 1770 a legal decision of the commissioners of the Great Seal reinstated Colman as acting manager, subject to the advice and inspection, but not the control, of his fellows. Powell meanwhile had died 3 July 1769.
On the resignation, 26 May 1774, by Colman of his post, Harris undertook the duties of stage-manager, which he held to until his death. He was accused of sacrificing to spectacle the artistic interests of the drama. He behaved generously to actors, however, and maintained a good reputation and some personal popularity.
