Portals is the debut solo EP of Metallica guitarist Kirk Hammett, released on April 23, 2022, through Blackened Recordings. The instrumental rock EP was released digitally as well as on CD and an exclusive ocean blue vinyl pressing for Record Store Day.

It consists of four instrumental tracks, described in a release as "a collection of gateways to myriad musical and psychic destinations." The songs were recorded between 2017 and 2020 in multiple locales ranging from Los Angeles to Paris to Oahu. Hammett added: "This music was created with what I describe as an Audio-Cinematic approach. They're soundtracks to the movies in your mind."

A single for the EP's third track "High Plains Drifter" was released on April 15, 2022, with an animated music video following April 22.
