Bulma (Japanese: ブルマ, Hepburn: Buruma) is a fictional character in the Dragon Ball franchise, first appearing in the original manga series created by Akira Toriyama. She made her appearance in the first chapter "Bulma and Son Goku", published in Weekly Shōnen Jump magazine on 19 June 1984, issue 51, meeting Goku and befriending him and traveling together to find the wish-granting Dragon Balls.

Bulma is the daughter of Dr. Brief, the founder of Capsule Corporation, a company that creates special small capsules that shrink and hold objects of various sizes for easy storage. Being the daughter of a brilliant scientist, Bulma is also a scientific genius, as well as an inventor and engineer. Along with creating the Dragon Radar, a device that detects the energy signal emitted by a Dragon Ball, Bulma's role as an inventor becomes important at several points in the series; including the time machine that brings her future son Trunks to the past.

Bulma is loosely based on the character Tang Sanzang from the Chinese classic novel Journey to the West. Bulma and Goku were the first pair of characters which were introduced in the manga and Toriyama stated that he subsequently introduced other characters in pairs because "that way, I'm able to explain the characters and their relationship to each other through their interactions. In my case, I feel that it isn't good to insert too much narration. I suppose Goku and Bulma are representative of that." He further added that "as a child, Goku doesn't know anything [of the world], so without Bulma, he'd be a character who didn't say anything." The author also claimed that when the series started, his editor at the time, Kazuhiko Torishima, wanted Bulma and Goku to form a romantic relationship.

Bulma's appearance in the series is not as consistent as the other characters as she often changes her hairstyle and clothing, being fashion-conscious. Her hair is usually depicted in a shade of fuchsia, although in the first chapter and the anime, her hair is turquoise. When asked about the first time Bulma's hairstyle changed, Toriyama said it was to show that three years had passed and because he personally liked girls with short hair. She sometimes wears clothing with either her name on it or the Capsule Corporation logo.

Her name "Buruma" is the Japanese pronunciation of "bloomer", a type of gym shorts worn by Japanese girls at school. As with most characters in the Dragon Ball series, Bulma's name is consistent with those of the rest of her family. All of Bulma's family members are named after underclothing of some sort. Her father's name is Dr. Brief, while her son and daughter are named Trunks and Bra (ブラ, Bura; "Bulla" in the English anime dub) respectively. Her mother is never named in the original series, being referred to only as "Bulma's Mother" (ブルマのママ, Buruma no Mama). However, when asked in 2004 what name he would choose if he were to name her mother, Toriyama suggested Panchy (パンチー, Panchī), a pun on panties. However, in the video game, Dragon Ball Z: Kakarot, Bulma's mother's name was revealed as Bikini (ビキニ, Bikini). Toriyama stated in an interview that Bulma's family has a "laissez-faire attitude, but Bulma has complete control over things."

Bulma was voiced by Hiromi Tsuru in all Japanese media until her death in November 2017. As a new voice actress at the time, she had to audition for the part. She also said that all her previous roles were well-behaved characters, but Bulma was easy to play because she is down-to-earth. In February 2018, Aya Hisakawa was announced as the new voice actress for Bulma.

In Funimation's in house English dub, Bulma is voiced by Tiffany Vollmer in the original Dragon Ball series. After Vollmer retired from voice acting, she was replaced by Monica Rial starting from Dragon Ball Z Kai.

Bulma's appearance in the anime is slightly different from the manga. In the manga version, her hair color is violet, while in the anime it is turquoise. Her long hairstyle stays shoulder-length as a teenager. She changes her hairstyle and cuts very often, and rarely wears the same dress for long periods. Many of the dresses that she wears bear her name or the Capsule Corporation logo.
