Jeanette Voerman is a character from the 2004 video game Vampire: The Masquerade – Bloodlines, an action role-playing video game developed by Troika Games and published by Activision. Set in White Wolf Publishing's World of Darkness setting, the game is based on White Wolf's tabletop role-playing game Vampire: The Masquerade. Created by Brian Mitsoda, an early version of her character was debuted in the E3 demo for the game as a means to attract the attention of journalists. In game, she is voiced by Grey DeLisle-Griffin, and on the box art and promotional artwork for the title, she is portrayed by Erin Layne. In live-action media, she has been portrayed by Whitney Moore in L.A. by Night.

She is one of the two vampire co-Barons of Santa Monica, California, and owner of the Asylum night club, the other being Therese Voerman. Though both regard the other as their twin sister, Jeanette is the alter of Therese, who due to abuse has dissociative identity disorder. Neither is dominant or aware they share the same body, and Jeanette actively works to sabotage Therese. In books for the role-playing game, it is established that Asylum has become a global franchise, with Jeanette and Therese alternatively managing either the Santa Monica or Hollywood locations.

Jeanette has been cited as one of the best aspects of Bloodlines, praised for both her character design and character, and introduction and portrayal helped set the tone of the game. While some have criticized her character's sexualization as fanservice intended for a male audience, others have argued it works in line with her character and cited her high popularity with fan communities who have portrayed her through cosplay. Her relationship with her other personality Therese has also been analyzed, both through the scope of their contrasting personalities and how their issues reflect perceptions of successful women in the modern age.

Jeanette was written for Vampire: The Masquerade – Bloodlines by Brian Mitsoda, who described her as a "combination of seduction, mischief, tragedy, and madness". One of the first character models made for the game, during the E3 demo Jeanette was not fully fleshed out. He wrote an early treatment of her as a "sexpot seductress fit for the E3 crowd to make the journalists collectively say 'garsh', blush and wave shyly", placing her in the game's strip club location to give players a quest to follow for the demo. As her character was developed and moved to another night club location in the game, Mitsoda was told to have her be more akin to her E3 version as the team leads felt she was not "sexy enough". Not wanting to undermine the character Jeanette had become, he wrote another character, Velvet Velour, to satisfy their mandates and placed her in the strip club.

As the game takes place in White Wolf Publishing's World of Darkness setting, Jeannette is defined as a vampire belonging to the Malkavian clan, who are inflicted with mental issues. Jeanette is the alter of Therese Voerman, a woman suffering from dissociative identity disorder, caused in response to abuse Therese suffered as a child. Both are fully developed personalities unaware of the other within the same body, and neither is considered the dominant personality, instead regarding one another as siblings. To portray it accurately, Mitsoda studied cases of the affliction, while other aspects of her character were based on an ex-girlfriend.

Jeanette is a pale woman with eyeshadow smeared heavily around her eyes and her blonde hair trussed into two pigtails on either side of her head. Her outfit consists of a sexualized Catholic schoolgirl outfit with a short blue skirt, white thigh-high stockings, a red choker, and brown shoes. Her underwear band is raised on each hip above the skirt, while her shirt is unbuttoned and tied below her breasts, exposing her cleavage and red bra. On the game's cover and promotional material she is portrayed by professional model Erin Layne, who was offered the job after a chance meeting with Shane DeFreest of Activision, the game's publisher. The photographs were taken by artist Tim Bradstreet, with the instructions for the photographs for the cover art to convey a "alluring and mysterious mood". In-game, Jeanette and Therese are both voiced by Grey DeLisle-Griffin, with the primary difference being delivery and tone.

Jeanette Voerman is a vampire in the 2004 video game action role-playing video game Vampire: The Masquerade – Bloodlines, developed by Troika Games and based on White Wolf Publishing's Vampire: The Masquerade role-playing game. Acting as co-Barons of Santa Monica within the vampire society, they are actively hostile to one another. The player can choose to do missions for either of them, with both wanting a pendant from the game's Ocean House Hotel location. If the player gives the pendant to Jeanette, she will task them with destroying an art gallery exhibit. Upon returning to the Asylum they are confronted by Therese, who threatens the player as the exhibit was hers, and it is then revealed both Jeanette and Therese are two personalities in the same body. Due to being ritually sexually abused by their father, their personality fractured in two, with Jeanette killing their father. Depending on the dialogue choices, the player can either side with either Therese or Jeanette, or convince the two to coexist. During the questline, the player can also romance and sleep with Jeanette, regardless of gender.

Jeanette later appears in the 2013 live-action role-playing book Mind's Eye Theatre: Vampire: The Masquerade and the 2018 5th edition rulebook for the Vampire: The Masquerade tabletop game, depicted by an uncredited model. The latter makes note that the Asylum has now become a global franchise, with Jeanette and Therese directly managing either its Santa Monica or Hollywood locations. She also appears in the 2020 livestream series L.A. by Night, portrayed by Whitney Moore. Set fifteen years after the events of Bloodlines, she and Therese still hold control over Santa Monica, though she tries to undermine Therese and to kill or seriously injure her. Meanwhile, in other video games, Activision included Jeanette's appearance as a skin as part of their "All-Start" character lineup for True Crime: Streets of LA's multiplayer mode.
