Dogmeat is the name given to various dogs featured in the post-apocalyptic role-playing game series Fallout. Dogmeat was introduced as an optional companion to the player character in the original Fallout (1997), and made a cameo appearance in Fallout 2 (1998). Other dogs named Dogmeat are featured and serve similar roles in Fallout 3 (2008), Fallout 4 (2015), and in the television series Fallout (2024).

Dogmeat was inspired by the unnamed dog of Max Rockatansky (Mad Max) from the 1981 post-apocalyptic film Mad Max 2. His initial name had been "Dogshit" and his ultimate name was derived from the opening scene of the 1975 post-apocalyptic film A Boy and His Dog, in which the main character Vic calls his dog Blood "Dogmeat".

This is one of several characters that have been tikified by Geekitikis and released as mugs, including Vault Boy, Dog Meat, Power Armor, Power Armor 2.0, and Deathclaw.
