Dan'l Druce, Blacksmith is a play by W. S. Gilbert, styled "A Three-Act Drama of Puritan times". It opened at the Haymarket Theatre in London on 11 September 1876, starring Hermann Vezin, Johnston Forbes-Robertson and Marion Terry. The play was a success, running for about 100 performances and enjoying tours and several revivals. It was popular enough to be burlesqued in a contemporary work, Dan'l Tra-Duced, Tinker, at the Strand Theatre. In an 1894 revival, Nancy McIntosh played Dorothy.

Sir William Schwenck Gilbert was an English dramatist, librettist, poet and illustrator best known for his collaboration with composer Arthur Sullivan, which produced fourteen comic operas. The most famous of these include H.M.S. Pinafore, The Pirates of Penzance and one of the most frequently performed works in the history of musical theatre, The Mikado. The popularity of these works was supported for over a century by year-round performances of them, in Britain and abroad, by the repertory company that Gilbert, Sullivan and their producer Richard D'Oyly Carte founded, the D'Oyly Carte Opera Company. These Savoy operas are still frequently performed in the English-speaking world and beyond.
