Bletiinae is a small-sized subtribe of orchids in the tribe Epidendreae of the subfamily Epidendroideae.

The tribe was initially categorized by John Lindley in 1840.

Bletiinae has been recognized as a subtribe to Arethuseae.

However, most of its genera were removed in 2005, and the subtribe moved to Epidendreae.
