The sentinel lark (Corypha athi) is a species of lark in the family Alaudidae found in Kenya and Tanzania.

The sentinel lark was formally described in 1900 by the German orthithologist Ernst Hartert based on a specimen collected on the plains of the Athi River in Kenya.

He considered it to be a subspecies of the rufous-naped lark and coined the trinomial name Mirafra africana athi.

[1][2] The sentinel lark is now treated as a separate species and placed in the genus Corypha.

This placement is based on the results of two molecular phylogenetic studies by a team of ornithologists led by Per Alström that were published in 2023 and 2024.
