The D'Oyly Carte Opera Company is a professional British light opera company that, from the 1870s until 1982, staged Gilbert and Sullivan's Savoy operas nearly year-round in the UK and sometimes toured in Europe, North America and elsewhere. The company was revived for short seasons and tours from 1988 to 2003, and since 2013 it has co-produced four of the operas with Scottish Opera.

Helen Carte Boulter, also known as Helen Lenoir, was a Scottish businesswoman known for her diplomatic skills and grasp of detail. Beginning as his secretary, and later marrying, impresario and hotelier Richard D'Oyly Carte, she is best remembered for her stewardship of the D'Oyly Carte Opera Company and Savoy Hotel from the end of the 19th century into the early 20th century.
