The Raso Lark (Alauda razae) is a small passerine bird with a highly restricted range, being found only on Raso islet in the Cape Verde Islands. This critically endangered member of the Alaudidae lives in highly arid terrain, and is considered one of the least known birds in the western Palaearctic region, due to its remoteness and the lack of much ornithological study on the archipelago as a whole.

Rasonkiuru (Alauda razae) on äärimmäisen uhanalainen varpuslintu, jota tavataan vain Rason pikkuruisella saarella Kap Verden saaristossa.
