A Link Monster (Japanese: リンクモンスター Rinku Monsutā) is a type of Monster Card introduced in Yu-Gi-Oh! VRAINS. The color of their card frame is dark blue with a hexagonal pattern similar to a honeycomb structure. These cards are placed in the Extra Deck and are Summoned by Link Summon. Link Monsters possess Link Arrows around the monster's artwork, which are a set of eight triangles that, when red, indicate which Monster Zones are Linked to it.

Link Monsters do not have Levels, and instead have a Link Rating. A Link Monster's Link Rating determines either the combined number of non-Link Monster Link Materials or the combined Link Ratings of Link Monster Link Materials (or any combination thereof) required to Link Summon it. A Link Monster's Link Rating is also equal to the number of Link Arrows it has. A Link Monster's Link Rating can be found next to its ATK, in the space occupied by the DEF on other types of Monster Cards. Because they do not have Levels, Link Monsters cannot be used for Ritual, Synchro, or Xyz Summons (unless otherwise specified). Effects that depend on a monster's Level, such as "Gravity Bind", "Burden of the Mighty", and "Roulette Barrel", have no effect on Link Monsters.

Link Monsters also do not have DEF, and as such, they cannot be changed to Defense Position and cannot be affected by any cards that would change them to face-down Defense Position, such as "Book of Moon".
