Twoflower is a fictional character featuring in some of Terry Pratchett's Discworld novels.

He comes from the overseas Agatean Empire, on the Counterweight Continent, where he works at an insurance (inn-sewer-ants) company and is the first tourist ever on the Discworld.

His adventures begin when he decides to visit the city of Ankh-Morpork, where he meets the inept wizard Rincewind whom he hires as a guide. Throughout the first two novels, he is followed by The Luggage, a box which moves on hundreds of little legs, carrying his belongings.

Twoflower is the optimistic-but-naive tourist (probably alluding to stereotypical American or Japanese tourists). He often runs into danger, being certain that nothing bad will happen to him, as far as he is not involved. He also believes in the goodness of human nature and that all problems can be resolved, if all parties show a good will and cooperate. Rincewind, of course, remains immovably convinced that Twoflower's IQ is comparable to that of a pigeon.

He was last seen as Grand Vizier of the Empire, under Emperor Cohen. It is not known if he still holds the position following Cohen's disappearance.

Twoflower appears in:

• The Colour of Magic
• The Light Fantastic
• Interesting Times

Twoflower also appears in the computer game Nethack as the leader of the Quest for the tourist class.
