A magnetic buckle includes two buckle bodies respectively have a magnetic attraction element fitted thereon. The two magnetic attraction elements bring the two buckle bodies to be magnetically detachably engaged with each other. A guide structure is formed on between the two buckle bodies. The two magnetic attraction elements and the guide structure together enable one of the two buckle bodies to move in different directions when it sequentially moves along an approaching path, within which the two buckle bodies are separate from each other, a contacting path, within which the two buckle bodies are brought to contact with each other, and a locating path, within which the two buckle bodies are brought to engage with each other. Thus, a user can conveniently magnetically engage the two buckle bodies with each other without the necessity of aligning them in advance or double-checking the engagement between them.
