The disclosed computer-implemented method for generating contextually meaningful animated visualizations of computer security events may include (1) detecting a security-related event that involves an actor and a target within a computing environment, (2) identifying certain characteristics of the security-related event that collectively describe a context of the security-related event with respect to the actor and the target within the computing environment, (3) generating, based at least in part on the certain characteristics of the security-related event, a graphical animation of the security-related event that graphically represents the context of the security-related event with respect to the actor and the target within the computing environment, and then (4) providing, for presentation to a user, the graphical animation of the security-related event to facilitate visualizing the context of the security-related event with respect to the actor and the target. Various other methods, systems, and computer-readable media are also disclosed.
