Kovojab (Kovojap, Kvolyab, Kopoyap) is a Bayono–Awbono language spoken in the highlands of Papua Province, Indonesia.
All that is known of Kovojab is a few hundred words recorded in Wilbrink (2004).
[1] The Kovojab word list in Wilbrink (2004) was originally recorded by Peter Jan de Vries.
Ethnologue gives the name Kvolyab as an alternative name for Awbono.
[2] However, Glottolog classifies Kovojab with Bayono rather than with Awbono.
