Voodoo Doll

A stock trick in any Hollywood Voodoo practitioner's arsenal is the Voodoo Doll, a tiny figurine created to vaguely resemble another person (sometimes using that person's hair or blood) which is then tormented in various ways, such as by being held over a fire or jabbed with needles. As the doll is damaged, so is the person connected to it, making it a wonderful long-range means of revenge.

In reality, so-called "voodoo dolls" are not a part of Vodou at all. They originated in Europe where they were called poppets, and Vodou's actual use of dolls (which have nothing to do with sympathetic magic) was most likely mistaken for this by European onlookers. And contrary to what Hollywood shows, they aren't just for torture. Some places in New Orleans and Haiti do sell "voodoo dolls" marketed to ignorant tourists, though.

Occasionally Played for Laughs in which the victim jerks around like a puppet when the doll is moved.

Examples of Voodoo Doll include:

Advertising

Many commercials like using voodoo dolls for humorous effect, such as the Sprint Commercial with the guy sticking pins into dolls representing overages and roaming fees.

Anime and Manga

Skip Beat! gives us Kyouko, who has quite the spread of voodoo dolls based off Sho. In the early part of the manga, she also has a large amount of Ren-themed ones as well. This later becomes a point when she gives Maria a realistic Ren-doll for her birthday. In more recent arcs, she has created a Reino doll in around 7 minutes.
Lime-iro Senkitan's Kinu Fukushima has personalized voodoo dolls for everyone aboard the Amanohara, and non-personalized ones for other occasions. Her favorite thing to do with them is stab nails through them to stop her friends from getting in her way, for love or otherwise.
Basil Hawkins in One Piece has them stored inside his body somehow. When attacked, he remained unharmed while the collateral damage took out buildings around him. Elsewhere, several unfortunate bystanders were flattened because they'd taken the blows for him. This also overlapped with a One winged Angel, since Hawkins can somehow become a gigantic living voodoo doll as well

Comic Books

In one issue of The Spectre, the eponymous hero fights against a Gypsy who uses one of these to attack people for no good reason.

Literature

In The Wise Man's Fear, mommets (figurines made of wax or clay and using bits of hair or blood) are key components in Malefesance magic. Kvothe uses an even more grisly version, stabbing an actual human corpse to maim people nearby.
In Witches Abroad Mrs. Gogol has a voodoo doll intended to be Lily, but when Granny Weatherwax gets in her way she makes it of her instead, stabbing it in the leg and making her stagger. Granny Weatherwax deals with it by sticking her hand into a torch, causing the doll to burst into flame.
In Sweets to the Sweet, Creepy Child Irma makes a voodoo doll of her abusive father, rendering him bedridden and unable to carry out his regular beatings of her. When his equally Jerkassish brother figures out what's going on, she claims the doll's just a bit of candy, and bites its head off to prove it...
This is how one of the witches defeats Septimus in Stardust.
In Fool Moon, Harry Dresden uses the same principle to temporarily disable a very powerful loup-garou. Saying precisely how would be a spoiler—and ruin a Crowning Moment of Funny.

Live-Action TV

Mimi once used one on Drew in an episode of The Drew Carey Show. Oddly it causes him pain in his arm although she's stabbing the doll somewhere further south.

Tabletop Games

In the Masque of the Red Death setting for Ravenloft, certain voodoo-inspired magic users can do this.

Video Games

These crop up fairly often in Monkey Island games. They tend to work at a limited range, and the spell to make them is a riff on the "Old, New, Borrowed and Blue" quatrain.

Web Comics

This Sinfest strip.
Gwynn of Sluggy Freelance made one of Riff and had some fun poking it in the eye, microwaving it, and throwing it in a desk drawer.
The Repository of Dangerous Things has a few including one "living" doll. It's kind of cute, but smacking it around turns out to be a very bad idea, as it can choose whom it depicts and is capable of self-mutilation (the doll can be repaired later, after all).
- For 25 cents Mama Zora can make a reversible version of this (see next pages).
Saturday Morning Breakfast Cereal has an improved version.
Questionable Content had one made by Hannelore accidentally. Then again, Hannelore sometimes spontaneously blacks out for a quick tirade in Black Speech when upset.

A variant of this trope appears in The Smurfs episode "Denisa's Greedy Doll" when Gargamel puts Greedy's apron on Denisa's doll and casts a spell on it so that whatever happens to the doll wearing the apron also affects Greedy.
