Charya tantra
Template:Four classes of tantra Charya tantra (Skt. caryātantra; Tib. སྤྱོད་རྒྱུད་, Wyl. spyod rgyud) aka Upayogatantra or Ubhayatantra (ཨུ་པའི་རྒྱུད་, u pa'i rgyud) is a classification of tantras within Tibetan Buddhism.
The vehicle of charya or ‘conduct’ tantra is so-called because it places an equal emphasis on the outer actions of body and speech and the inner cultivation of samadhi. It is also called the ‘tantra of both’ (Skt. ubhaya tantra) because its view conforms with that of yoga tantra, while its conduct is similar to that of kriya tantra.

- the second of the three outer tantras within the nine yanas classification of the Nyingma school
- the second of the four classes of tantra according to the Sarma schools.
