MechWarrior is often used as an alternative moniker or brand name for BattleTech-related products and publications. It can refer to:
- The MechWarrior: Dark Age and later MechWarrior: Age of Destruction (MWDA/MWAoD) boardgame and its setting, a miniatures-based collectible game by WizKids using the Clix system and rules. A distinct boardgame from Classic BattleTech, it was initially set some 60 years ahead of the classic BattleTech universe timeline and had its own novel line (see below). It was discontinued as a separate game, and its setting, timeline and novels were since overtaken by and incorporated into the classic BattleTech game line.
