Arethuseae is a mid-sized tribe of orchids in the subfamily Epidendroideae.

This tribe was initially categorized by John Lindley in 1840.

Its largest subtribes are Arethusinae and Coelogyninae.

Bletiinae was once considered a subtribe of Arethuseae, but it was moved to Epidendreae in 2005.

[2] Sobraliinae has been considered a subtribe of Arethuseae, but is now recognized at the rank of tribe within the subfamily Epidendroideae.
