This is a list of dinosaurs whose remains have been recovered from Asia, excluding India, which was part of a separate landmass for much of the Mesozoic (See List of Indian and Madagascan Dinosaurs for a list of Dinosaurs from India). This list does not include dinosaurs that live or lived after the Mesozoic era such as birds.
- The genus must appear on the List of dinosaur genera.
- At least one named species of the creature must have been found in Asia.
- This list is a complement to Category:Mesozoic dinosaurs of Asia.

- Amtosaurus magnus: An indeterminate ornithischian that may be either a hadrosaurid or an ankylosaurid.
- Antarctosaurus: A. jaxarticus from Kazakhstan has been referred to this genus, but such an assignment is probably incorrect.
- Asiamericana asiatica: Known only from teeth, it has been suggested to a fish, a spinosaurid, or a species of Richardoestesia.
- "Bakesaurus": Often included in lists of dinosaurs as a nomen nudum, but may simply be a junior synonym or misspelling of Bactrosaurus
- "Balochisaurus malkani": A supposed saltasaurid titanosaur from Pakistan. A paper published in 2021 could make this, as well as other informal Pakistani dinosaurs, valid.
- Beipiaognathus jii: Described based on a chimeric holotype including compsognathid elements.
- "Changdusaurus laminoplacodus": A potential stegosaur; its remains are now thought to be lost.
- Chienkosaurus ceratosauroides: A possible junior synonym of Szechuanosaurus.
- "Dachongosaurus yunnanensis": Reportedly a Cetiosaurus-like sauropod.

- "Eugongbusaurus" wucaiwanensis: Coined for a referred species of Gongbusaurus. This name is said to have been leaked accidentally.
- "Futabasaurus": A supposed tyrannosaur from Japan. If formally described, it would require a new name as Futabasaurus has already been used for a plesiosaur.
- "Gadolosaurus": The name is an incorrect romanization of the Russian word gadrosavr, meaning hadrosaur, and was not meant to be a new generic name. It may have been a synonym of Arstanosaurus.
- Gobiceratops minutus: May be a growth stage of Bagaceratops.
- "Gspsaurus pakistani": One of several informally-named titanosaurs from Pakistan.
- Gyposaurus: Type species was found in South Africa and may be a synonym of Massospondylus. The Asian species may be identical to Lufengosaurus.

- "Heilongjiangosaurus jiayinensis": May be a synonym of Charonosaurus and/or "Mandschurosaurus" jiayinensis.
- "Khetranisaurus barkhani": Also spelled "Khateranisaurus". Both spellings remain informal.
- "Koreanosaurus": No relationship to the formally-named ornithischian of the same name (see above). Later renamed "Deinonychus" "koreanensis", but this generic assignment is likely incorrect.

- Lukousaurus yini: Sometimes thought to be either a theropod or a pseudosuchian.

- "Marisaurus jeffi": Potentially closely related to "Balochisaurus" and "Sulaimanisaurus".
- "Megacervixosaurus tibetensis": A sauropod. Its classification is uncertain, but it may be a titanosaur.
- "Microdontosaurus dayensis": May have been formally described a different name, but it cannot be proven.
- "Ngexisaurus dapukaensis": Sometimes known as Megalosaurus "dapukaensis", but it is unlikely to belong to this genus.
- Nomingia gobiensis: Notable as one of the first non-avian dinosaurs found with a pygostyle. It may, however, be a synonym of Elmisaurus.
- "Nurosaurus qaganensis": Noteworthy for preserving the first stress fracture found on a sauropod foot. Presented as "soon to be described" in 1992 but remains a nomen nudum to this day.
- "Oshanosaurus youngi": An early sauropod. Has been confused with heterodontosaurids and Eshanosaurus.
- "Otogosaurus sarulai". Very little is known about it. Although it often appears on lists of dinosaurs as a valid taxon, there is no proof it was ever validly named.

- Platyceratops tatarinovi: May be a junior synonym of Bagaceratops.

- "Ronaldoraptor": An oviraptorosaur with a tall, rectangular crest. Named in a book described as a field guide for time travelers.
- "Sanchusaurus": Said to be potentially synonymous with Gallimimus.
- "Sangonghesaurus": Possibly a synonym of Tianchisaurus, if it is not a basal ornithischian.
- Shuangbaisaurus anlongbaoensis: May be an individual variation of Sinosaurus.

- "Vitakrisaurus saraiki": A noasaurid from the same layers as "Vitakridrinda".
- "Yibinosaurus zhoui": May in fact be a second species of Gongxianosaurus.
- "Yunxianosaurus hubeinensis": Mentioned in a scientific paper as a temporary placeholder name. Further work is needed to determine whether it deserves a formal name.
- Zhongornis haoae: Known from a juvenile skeleton. It is usually thought to be a basal avialan but one hypothesis is that it is a non-avian scansoriopterygid.
- Zhongyuansaurus luoyangensis: Potentially a synonym of Gobisaurus.
