An anal vibrator is a vibrator designed for sexual stimulation of the anus of both men and women. All anal vibrators have one common feature: they produce a vibrating effect in the rectum for pleasurable sensations.

Anal vibrators differ from other types of vibrators in that they have a flared base to prevent possible loss in the rectum.^[1] The average size of an anal vibrator is smaller than vibrators intended for vaginal penetration and may vary from 4-6 inches long and about 1 inch wide. As well as other vibrators designed for external and internal stimulation, anal vibrators are usually battery operated: the batteries may be inside the unit or connected by wire to a power pack.

Unlike anal dildos, such as butt plugs, anal probes and anal beads, vibrating anal toys may produce various stimulating effects: rotating, vibrating or pulsating, and can have different speed or vibration levels to regulate and adjust the vibrator to various sensations.
