10,000 (ten thousand) is the natural number following 9,999 and preceding 10,001.

Many languages have a specific word for this number: in Ancient Greek it is μύριοι (related to the word myriad in English), in Aramaic ܪܒܘܬܐ, in Hebrew רבבה (revava), in Chinese 萬/万 (Mandarin wàn, Cantonese maan6, Hokkien bān), in Japanese 万/萬 [man], in Khmer ម៉ឺន [meun], in Korean 만/萬 [man], in Thai หมื่น [meun], and in Malayalam പതിനായിരം (patinayiram). It is often used to mean an indefinite very large number.

The Greek root was used in early versions of the metric system in the form of the decimal prefix myria-.

The number 10000 can also be written 10,000 (UK and US), 10.000 (Europe mainland), 10 000 (transition metric), or 10•000 (with the dot raised to the middle of the zeroes; metric).
