Blackmoor is a supplementary (product designation TSR 2004) of the original edition of the Dungeons & Dragons fantasy role-playing game written by Dave Arneson (with a foreword by Gary Gygax).

Blackmoor, the second supplement to the original D&D rules, is known for its introduction of rules for underwater adventures and hit location, and the addition of the monk and assassin character classes.

Dave Arneson named the booklet after his original role-playing campaign world, Blackmoor. It has additional rules, monsters, treasures, and the first role-playing game adventure ever published, The Temple of the Frog. Despite the name, the supplement included almost no information on Arneson's version of the world.

Blackmoor added two new character classes to the game: the assassin, a sub-class of the thief; and the monk, a "monastic martial arts" sub-class of the cleric, intended to be a hybrid of the fighter and thief classes. The book also introduced a hit location system, wherein each individual body part of a character or monster was assigned its own hit points. The odds of hitting any specific body part changed depending on the character's height and weapon reach. If any individual body part was brought down to zero hit points, the creature would be crippled or killed.
