Pat is a fictional character in Lewis Carroll’s 1865 book Alice's Adventures in Wonderland. He appears in the chapter "The Rabbit Sends in a Little Bill." He works for the White Rabbit like his friend Bill the Lizard. Carroll never gives any description of the character other than being a gardener, and his species has been widely debated, with evidence showing he is likely to be a monkey or a guinea pig.

Alice's Adventures in Wonderland is an 1865 English children's novel by Lewis Carroll, a mathematics don at Oxford University. It details the story of a girl named Alice who falls through a rabbit hole into a fantasy world of anthropomorphic creatures. It is seen as an example of the literary nonsense genre. The artist John Tenniel provided 42 wood-engraved illustrations for the book.
