A vengeful spirit is one that acts violently to avenge something a wrong done to them. While they are generally ghosts, the spirit may belong to someone still alive but close to death, such as Callie in 3.05 Bedtime Stories. This group does not include the spirits of people continuing acts of evil that they perpetrated while alive, like the Hookman Jacob Karns or serial killer Dr. H.H. Holmes, or those acting for their own ends like Maggie Thompson in 2.11 Playthings.
Although vengeful spirits can essentially target those who committed crimes against others, their judgements can be warped by their time dead; as an example, a ghost who targets those who kill family members cannot distinguish between brothers who killed their father to collect on his life insurance or a girl whose cousin died in a car accident where she was driving.
- Tessa: "Dean. How do you think angry spirits are born? They can't let go and they can't move on. And you're about to become one. The same thing you hunt."2.01
Spectres are a particular type of avenging ghost, that possess a person, senses their grudges and makes you act against the person who wronged you. they can be distinguished from other vengeful spirits, or ghosts in general, in that they leave behind green rather than black Ectoplasm. Vance Collins in 8.06 Southern Comfort was an avenging ghost. Both Vance, and the last spectre Bobby encountered, according to his journal, rose after someone desecrated their grave.
It was initially unclear where dispatched ghosts go to. In 2.16 Roadkill Sam admits "My dad always said it's like death for spirits. But the truth is, we never know." Dean tells Melanie Golden in 7.07 The Mentalists that burning a ghosts bones may be painful for it. Bobby also expressed to Annie Hawkins the belief that this is death for spirits, though he told Sam and Dean that he'd see them on the "other side" before being put to rest. In 8.19 Taxi Driver, it is revealed by rogue reaper Ajay that reapers collect spirits once their remains are burned and they are taken to what is supposed to be their final resting place. However, if the reaper is influenced by an outside source such as Crowley, the soul may be taken somewhere else instead.

Dispatching Vengeful Spirits
- Sam appears to push the spirit of Dirk McGregor out of a high school student by pouring salt into his hand and filling or covering her mouth with it in 4.13 After School Special, although this doesn't destroy it.
- The boys commonly dispatch a spirit by salting and burning its corpse.
- In some cases, even if the corpse is destroyed, some remnant of bodily material may remain which must be burned. Examples include an antique doll containing some of Melanie Merchant's hair in 1.19 Provenance, the lock of Dirk McGregor's hair in 4.13 After School Special, or P.T. Sandover's gloves containing skin cells in 4.17 It's a Terrible Life.
- Spirits can be attached to an object: Mary Worthington was trapped inside a mirror in 1.05 Bloody Mary, Bobby was attached to his whiskey flask and Vance Collins was attached to his Indian Head Penny as well as his bones.
- Vengeful spirits may be at rest once they are avenged or heard (i.e. Peter Sweeney and Callie).
