Planet Earth (地球 惑星, Chikyū Wakusei), also called Dragon World (ドラゴン ワールド, Doragon Wārudo), is a planet inhabited by Earthlings: Animals, Humans, and Monsters. It is the home of the Z Warriors and the main setting for the entire Dragon Ball series. It is also the main setting for other Akira Toriyama series including Dr. Slump, Neko Majin, Wonder Island, Tomato, Today's Highlight Island, and Pink.
Earth is very advanced (though the Dragon Ball, Dragon Ball Z, and Dragon Ball GT series take place in the 700 and 800s Ages; see age system below). Flying vehicles, capsules that can shrink inanimate objects down to pocket size, robots, and other near-future science fiction staples are common-place on Earth. The architecture is also more advanced. The buildings are usually rounded, often employing spherical or ovoid sections held aloft by a cylindrical stem. Certain elements of magic also coexist with the advanced science.
Politically, Earth has a planet-wide constitutional monarchy. Chichi mentions in The Legacy of Goku video game series that a presidential office exists. Earth is divided into 43 "sectors" and led by the World King. The English dubs mention that each sector is ruled by a king and that World King is only the king of his particular sector. There is also a large military force on Earth for use when threats loom over the world. The dating system is also quite different. While the length and divisions of the year seem to be identical to the Gregorian Calendar, years are reckoned by the age system (エイジ, eZiji; usually interpreted as the Christian Anno Domini: "A.D." by fans, or as "Age" or "Before Age", according to the Daizenshu and other various guides). The standard currency is the Zenie, which is mostly mentioned at the Tenkaichi Tournament and in the Budokai video game series. In the Tenkaichi Tournament in the Budokai video game series, Second Place awards you 5000 Zenie and First Place awards you 10000 Zenie.
With the exception of most of the notable characters in the series, most of Earth's inhabitants seem to suffer from Sunnydale Syndrome. Despite the obviously staggering power of the Saiyans and a select few Humans, most of the populace believes that Mister Satan is the world's strongest fighter (after the events of the Cell Games). They continue to believe this even after several pathetic losses to various foes, due in part to Satan's ability to convince them that his opponents cheated somehow. Even when directly confronted with evidence directly contradicting Satan, they continue to believe him responsible for many of the major victories in the series.
In the Dragon Ball universe, all planets benefit from an appointed deity. Throughout most of Dragon Ball, the god of Earth was Kami (called Guardian of Earth in the English dubs), but later that position is given to Dende after Kami fuses with Piccolo to battle against the Androids and Future Cell. Because both Kami and Dende are Namekian, they have the ability to create seven Dragon Balls that grant wishes if all seven are collected. These wishes are used regularly throughout Dragon Ball for many various things, usually bringing people back to life.
Earth is primarily dominated by Humans. With the exception of the uncommon hair colors and occasionally odd features (ranging from longer lifespans, to werewolfism, to Tenshinhan's third eye), Dragon Ball Humans are identical to their real world counterparts. Humans in Dragon Ball seem to be able to utilize or be affected by certain elements of magic. Toriyama himself has admitted to lack of forethought or planning when it comes to the details of Dragon Ball's story, which accounts for some of the strange occurrences. Due to the biological similarities Saiyans have to Humans, the two races are able to interbreed producing hybrids.
When compared to other species of Dragon Ball, the average Human is significantly weak. (One drastic exception to this rule is Uub although it can be argued that, since he is the reincarnation of Kid Buu, he is not human in the strictest sense.) It is said that a single Saiyan infant would be capable of destroying the general population on its own. However, a select few humans have learned to use Ki and are among the strongest beings in the universe. Even with such abilities, this select group of humans are still considerably weaker than many aliens with the same Ki-manipulation abilities. As stated in the manga, it's possible for any human to use their Ki and gain powers like the Z Warriors. For example, Son Gohan easily teaches Videl how to use Ki to fly.
Though less common, intelligent anthropomorphic (and sometimes non-anthropomorphic) Animals such as Oolong and Puar are integrated into the population and are well-adjusted and accepted as people. (This is similar to fairy tale animals in European fiction, such as the Three Little Pigs, Puss in Boots, etc.) Even so, the anthropomorphic population sees a drastic and noticeable decline over the course of the series, but it never goes away completely.
Creatures and devices used on Earth also vary greatly, as is common in works such as Dragon Ball. Dinosaurs and other extinct creatures in the real world still roam Earth freely, while the characters fly around in futuristic levitating cars and houses that can be shrunk down to the size of portable Hoi Poi Capsules.
The first known series-related tragedy took place some 300 years prior to the beginning of Dragon Ball. When Piccolo Daimao first made himself known to the world, he spawned several underlings and sent them to destroy a city and all its inhabitants. Outside that city was Mutaito's dojo, where he and his students trained. The underlings attacked the dojo, and in the aftermath, the monsters and all but two of the students were dead. These two students, Muten Roshi and Master Shen, and Mutaito managed to live to fight another day and went their separate ways until Mutaito's rematch with Piccolo Daimao, by which time most of Earth's population had been eradicated by the evil Namekian. In his final battle, Mutaito sealed Piccolo Daimao away with the Evil Containment Wave, after which Earth returned to normal until Piccolo Daimao's brief resurgence as a villain in 753 Age.
Over the course of the series, Earth and its population went through many trials and tribulations. When Garlic Jr. arrived, he used the Black Water Mist to infect Earth's population and transform them into evil beings. In the Cell Saga, Future Trunks told Goku about the Androids, who, he explains, killed off most of Earth's population in his timeline. Coupled with the threat of the Androids, Cell killed millions and proceeded to host a martial arts tournament, in which failure to defeat him meant Earth's certain doom. In the Majin Buu Saga, Majin Buu destroyed entire cities at a time. When he transformed into Super Buu, he was able to effect a nearly perfect genocide upon Earth with a single attack. Finally, Kid Buu used a powerful energy blast to blow up Earth. It was eventually restored with the Dragon Balls only to be threatened again by the evil Baby years later in Dragon Ball GT. The gates of Hell were also opened by Dr. Gero and Dr. Myuu, but eventually closed. When the Evil Dragons attacked, Earth and its population once again came close to extinction, only to once again be saved by the Z Warriors.
Kid Boo has the distinction of being the only villain in the entire Dragon Ball series to actually succeed in destroying the planet; Vegeta, Freeza, and Cell all claimed that they would, but were thwarted by either Son Gohan or Future Trunks Brief before doing so.

 Real world references
Main article: List of real world references
- In one scene during the Emperor Pilaf Saga, Pilaf is dancing around holding a globe that has the continents in the same shape as the real world, not of the Earth of Dragon Ball.
- Krillin is reading a newspaper that looks to be titled 'USA News' during the Tournament Saga. This is odd because the USA does not exist on the Earth of Dragon Ball.
- White was once implied to be from Russia (or more specifically, the Soviet Union).
- Murasaki hides behind an American flag.
- In the final episode of the General Blue Saga, Arale knocks Blue all the way to Egypt.
- In "Which Way to Papaya Island?", when Son Goku and Konkichi are at the Yahhoy Airport, a sign in the background lists several real world cities.
- When trying to figure out a way to avoid Piccolo Daimao and his sons, Oolong exclaims that he heard flights to the Caribbean were cheap that time of year.
- In "Global Training", Piccolo is seen practicing his mental techniques on the pyramids of Egypt in preparation for the arrival of the Saiyans.
- In Dragon Ball Z: Super Android 13!, Kuririn, Muten Roshi, Future Trunks Brief, and Oolong are in line to see a beauty pageant where they mention Russia, Spain, France, and Australia, even though none of these places are supposed to exist in the Earth of Dragon Ball. (It should be noted that those continents were added in the dub.).
- In Dragon Ball Z: Broly: The Legendary Super Saiyan, Gohan calls Kuririn the best singer in Japan. This was in the original Japanese dub.
- In Dragon Ball Z: Bojack Unbound, the location of the fight between Future Trunks and Kogu greatly resembles London, England.
- Dr. Slump, a series that takes place in the same universe, has several real world references as well.
