The characters of Ghost Whisperer number pretty high over the series, and almost all of them get a decent amount of characterization given the ghost-of-the-week episode basis. For the sake of cleanliness, characters both living and dead will be divided by season.
The main character of course. Her life would otherwise be quite happy, as she has a thriving marriage with a handsome husband, a nice house, and the job she enjoys—were it not for the ghosts that regularly make her life hell. She inherited the ability to see ghosts from her grandmother, Mary Ann, who called them "earthbound spirits". These spirits have unfinished business with the living, and thus stay on earth until it's resolved, which is Melinda's other job of sorts.
- Blessed with Suck/Cursed with Awesome: Melinda refers to her ability as a gift, and had to have her grandmother's input to help see it as something worthwhile, as much of her young life she thought it made her a freak. Now that she's grown, freak or not, ghosts still come to her, and she still has to cross them over. On the upside, it's genuinely helpful to everyone involved most of the time. Have fun finding an episode that isn't a Tear Jerker.
- Brought Down to Normal: After a car accident in Vanishing. Subverted at the end of the episode, when it's revealed that she has not lost her ability to see ghosts, but that something is "sucking" them.
- Broken Bird: Melinda's own life is not without casualties. Sometimes this makes her an Iron Woobie, but she's shown to be very torn up about the losses in her life most of the time.
- Buxom Is Better/Sexy Backless Outfit: Early seasons put Melinda into some very...nice clothing.
- The Call: Not just her ghost-riddled daily life. Supernatural forces literally tell Melinda that she is the only one who can save certains souls before the end of season one.
- Dreaming of Things to Come: Inverted, as she tends to see the past events of ghosts, rather than the future ones. However, in Season 5, when she is pregnant, she does have recurring nightmares of her baby's fate.
- The Empath: Melinda is aware that ghosts can affect people and herself in more ways one, and commonly notes a presence even when she can't see it. In one episode she uses touch to trigger a vision on purpose to find out who killed a ghost.
- Go into the Light: Her main goal, as a resolution of Unfinished Business.
- Happily Married: For the most part
- The Heart: Melinda's ability pretty much requires her to be this, as until she can make them feel better, ghosts will regularly screw around and cause harm.
- I See Dead People: As per her "gift"
- I Just Want to Be Normal: For a little while during her youth, as ghosts determinedly trying to talk to her was causing problems with her social life. She is now being made fun of because of her power to see ghosts.
- Law of Inverse Fertility: Downplayed in "Deadbeat Dads", she and Jim attempt to have a child to no success, as she has a miscarriage. Eventually, this is turned around when she has Aiden.
- Loners Are Freaks: She is being called a freak by an Alpha Bitch since high school in "Mean Ghost" in a flashback.
- Long-Lost Relative: To Gabriel, who came from her father's side and was in a psych ward.
- MuggleMage Romance: Is married to Jim, who has no power of his own.
- The Soulsaver: Downplayed, however, she does this trope in a way by convincing and helping ghosts cross over, along with helping them come to terms with circumstances and or make amends with their loved ones.
- Surrounded by Idiots: Melinda herself is actually very intelligent and resourceful, and thankfully usually has the sense to pick up a weapon when someone living might hurt her. It's just that the people she has to cooperate with can be kind of dense, sometimes seemingly on purpose.
- Unlimited Wardrobe: In earlier seasons, though her wardrobe had to be toned down because of Executive Meddling.
- Played By: David Conrad
Melinda's husband, and one of the only people to be fully aware of her powers, how she uses them, and to never be skeptical about it. He starts out as a firefighter with connections to the police office, before becoming a paramedic.
- Identity Amnesia: When he becomes a step-in, he loses all memory of who he was as Jim or as Sam. Jim starts to come back to him though.
- Killed Off for Real: He comes back though. Sort of.
- Mr. Fanservice: Not to the extent of Melinda, but he has his fair share of scenes where he's shirtless and occasionally and beautifully bareass naked.
- MuggleMage Romance: Is married to Melinda, and has no power of his own.
- Sidekick: His connections to the police office are what tends to make many episodes possible where research is required. Unlike a lot of shows, Jim actually does get some strain and complains that he's running out of favors with them.
- Played By: Aisha Tyler
Andrea is Melinda's best friend and coworker in the shop. After Season One, she's replaced by Delia.
- Bait-and-Switch: Even worse and more painful than other times in the show. In the Season One finale, when she thinks her brother is on a doomed plane, she gets in her car and rushes to see him, only for the plane he was supposed to be on to crash into her car and kill her. We're led to believe Melinda is trying to tell Andrea her brother is dead—but it turns out Andrea's the ghost.
- Black Best Friend: Plays this role to Melinda being one of her few confidantes
- Dead All Along: See the Bait-and-Switch entry
- Sidekick: Played this role initially until she was replaced by Delia
- Played By: Jay Mohr
A very, very smartass professor who occasionally lapses into Motor Mouth. He claims to not believe in any of the supernatural things his job as a professor covers, but is nonetheless very knowledgeable of it. In season two, Melinda finally tells him her ability after severl occasions of dodging questions from him.
- Rejected Apology: To his late wife, who cheated on him despite loving him very much—she wouldn't have let him find this out, however, Gabriel convinced her to. This is what prevents her from crossing over.
- Skeptic No Longer: His wife has been haunting him for a long time. When she gets vocal about it though, Melinda spills and he becomes a believer.
- Played By: Camryn Manheim

- Glamorous Single Mother: Subverted
- Mama Bear: When she finds out someone tampered with Ned's records, almost costing him a chance at private school.
- Sidekick: Plays this role to Melinda in Season 2

- I See Dead People: He doesn't see them, instead, he hears them
- Near-Death Experience: A part of how he gains the ability to hear ghosts
- Played By: Connor Gibbs
Melinda's Son who makes an appearance in Season 5
- Bait-and-Switch: Oftentimes it isn't apparent that someone's a ghost until someone walks right through them.
- Empathic Shapeshifter: Quite often, a ghost will start out looking anywhere from mildly disturbing to incredibly terrifying. Melinda notes that this a result of their mental state—if a ghost has just died, and/or is confused with their situation, they usually appear in the form they were when they died, that is to say, frozen over, with a burnt face, or no face at all in the cases of two separate ghosts. On other occasions, a ghost may appear blurry or distant to Melinda for similar reasons. As Melinda gets further into the case and figures more things out, they can appear more clearly and more close to a normal form rather than anything malevolent, as they understand more. This can be a surprisingly useful tool to know when a character in the show may be incredibly malicious or evil—if they're doing bad things and look completely normal, then it's bad news.
- Demonic Possession: a variant and a subversion. All ghosts are capable of inhabiting bodies. One ghost inhabits the body of another recently dead against his will, and begins controlling the corpse, which eventually starts to deteriorate and forces him out. A ghost can also become a "step-in" as Jim does, but this will lead to memory loss and in worse cases suicide. There's also hypnotic suggestion, where a ghost will whisper (or scream) into a person's ear and affect their emotions and actions. One case of this got so bad that it very much seemed like the living bodies of two victims were being controlled, though as Professor Payne notes "only demons possess people". Despite this distinction, at least one man gets full-on possessed by his dead girlfriend at night.
- Played By: June Squibb
