Azaborane usually refers a boranes, borane Cluster chemistry, cluster where BH vertices are replaced by N or NR (R = H, organic substituent). Like many of the related boranes, these clusters are polyhedra and can be classified as ''closo-'', ''nido-'', ''arachno-'', etc.
Within the context of Polyhedral skeletal electron pair theory, Wade's rules, NR is a 4-electron vertex, and N is a 3-electron vertex. Prominent examples are the charge-neutral ''nido''-NB10H13 (i.e. (NH)(BH)10) and ''closo''-NB11H12 (i.e. (NH)(BH)11).{{cite journal, author=P.

Azaboranes can also refer to simpler compounds including iminoboranes (formula = RN=NR') and borazines.
