Ketchup is a peppy duck villager in the Animal Crossing series. After her debut in Doubutsu no Mori e+, she would remain absent from the series until Animal Crossing: New Leaf - Welcome amiibo. Her name comes from tomato ketchup (tomato sauce), a condiment oftentimes used on sandwiches. This also refers to her appearance, which resembles a tomato. Her catchphrase is the name of a snooty hippo villager.

In New Horizons, Ketchup has the play hobby and can run around with her arms extended at any time, rather than only outside Resident Services during a scripted activity with a group of villagers.
