Provided are a fall detection apparatus and method. The fall detection method may include measuring first to third accelerations corresponding to a user, measuring first to third angular velocities corresponding to the user, determining an acceleration value for the user based on at least one of the first to third accelerations, determining an angular velocity value for the user based on at least one of the first and second angular velocities, determining an angle value for the user based on at least one of the first to third accelerations, calculating a triangle feature using the acceleration value, and detecting a fall of the user based on at least one of the acceleration value, the angular velocity value, the angle value, and the triangle feature.
