Medals are preset rewards or bonuses given in Halo 4's, Multiplayer mode, when players perform specific actions. These usually involving the killing of enemies or rival players. Medals now take on a more icon or emblem-like appearance rather than the realistic medal appearance in Halo: Reach. As there is no longer campaign scoring; medals are not awarded in campaign.

Multi-kill medals in Halo 4 are now slightly easier to achieve, with the allotted time between kills increased from 4 seconds to 4.5 seconds. Weapon Spree medals have been discontinued, while several weapon kill and assist medals have been added.
