Untitled Goose Game is a 2019 puzzle stealth video game developed by House House and published by Panic. In the game, players control a goose who bothers the inhabitants of an English village. The player must use the goose's abilities to manipulate objects and non-player characters in order to complete specific objectives and progress through the game.

Untitled Goose Game originated from a stock photograph of a goose that a House House employee posted in the company's internal communications. This sparked a conversation about geese; the team put the idea aside for a few months until they realized that it had the potential to be a fun game. Inspired by Super Mario 64 and the Hitman series, House House worked on combining stealth mechanics with a lack of violence to create humorous in-game scenarios. The game's unusual name came from a last-minute decision in preparing the title as an entry for a games festival, and stuck.
