Imagine (printed under the long title Imagine: Adventure Game Magazine) was a British monthly magazine dedicated to the first edition Advanced Dungeons & Dragons and Dungeons & Dragons role-playing game systems published by TSR UK Limited.

Don Turnbull was cited as publisher and Paul Cockburn as assistant editor for the majority of the life of the publication.

Neil Gaiman wrote film reviews for several issues of Imagine in the early part of his career, taking over from Colin Greenland, and had his first short story "Featherquest" published here in May 1984.

This was briefly revived as a second story arc titled Auchter's Axe in issues 29 to 30 prior to the magazine's cancellation.

When some TSR UK staffers were made redundant, they started the publication Game Master to try to maintain the experience of Imagine and some of its popular features, such as Pelinore; that magazine also published articles containing details on the closure of Imagine, which criticized Gary Gygax and TSR.
