The Bab Ballads is a collection of light verse by W. S. Gilbert (1836–1911), illustrated with his own comic drawings. The poems take their name from Gilbert’s childhood nickname. He later began to sign his illustrations "Bab". In writing these verses Gilbert developed his "topsy-turvy" style in which the humour is derived by setting up a ridiculous premise and working out its logical consequences, however absurd. The ballads also reveal Gilbert's cynical and satirical approach to humour. Gilbert wrote most of the "ballads", and first published a collection of them in book form, before he became famous for his comic opera librettos written in collaboration with the composer Arthur Sullivan.

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.
