Opera della Luna (OdL), founded in 1994, is a British touring theatre troupe of actor-singers focusing on comic works. Led by artistic director Jeff Clarke, it takes its name from Haydn's operatic setting of Goldoni's farce Il mondo della luna. The company presents innovative, usually zany and irreverent, small-scale productions and adaptations of Gilbert and Sullivan, Offenbach and other comic opera and operetta, in English. OdL is a registered British charity.

After directing his own touring opera ensemble in the 1980s, Clarke formed OdL in 1994. He soon began producing touring adaptations of Gilbert and Sullivan operas and well-known operettas, like The Merry Widow, Die Fledermaus and several Offenbach pieces. The company has also presented shows and concerts on the QE2 cruise ship and elsewhere, annual Christmas pantomimes and summer or festival productions. Other pieces have been by Donizetti, Verdi, Strauss, Mozart and Bernstein.

The company has generally undertaken two major tours each year, visiting more than a hundred mid-scale venues throughout the UK in some years. Occasionally the company has toured overseas. Clarke directs all of the productions, which are mostly small-scale adaptations performed without chorus, accompanied by a small orchestral ensemble.
