A khoroo (Mongolian Cyrillic: хороо) is an administrative subdivision of Ulaanbaatar, the capital of Mongolia. The term is often translated as subdistrict or microdistrict, although the latter might lead to confusion with khoroolols. A khoroo is below the level of a düüreg (district).

There were 121 khoroo until 2007, when the number increased to 132. Each khoroo has an identifying number within its düüreg, although some may also have a name (e.g. Narnii zam 13 or Rashaantiin 18). As of 2013 there is a total of 151 khoroo.
