Dō (堂, temple, shrine, hall, reception room; also shop, store^[1]). It is very often used in Japanese Buddhism as a suffix in the name of some of the many buildings that can be part of a Japanese temple compound. (Other endings, for example -den as in butsuden, exist.) The suffix can be the name of a deity associated with it (e.g. Yakushi-dō, a name customarily translated as "Yakushi Hall") or express the building's function within the temple's compound (e.g. hon-dō, or main hall).^{[note 1]}

Some words ending in -dō are Butsu-dō, hō-dō, hon-dō, jiki-dō, kaisan-dō, kō-dō, kon-dō, kyō-dō, mandara-dō, miei-dō, mi-dō, sō-dō, Yakushi-dō and zen-dō. With some exceptions, for example the words hondō, hokke-dō and kon-dō, these terms do not indicate any particular structure.

The suffix is used sometimes also in a lay context, as for example in the word shokudō (食堂, lit. food building, meaning restaurant or cafeteria).

A dō's size is measured in ken, where a ken is the interval between two pillars of a traditional-style building. A kon-dō for example is a 9x7 ken.^[2] The word is usually translated in English as "bay" and is better understood as an indication of proportions than as a unit of measurement.
