Riley 'Kestrel' was a brand name applied by the Riley Motor Car Company and its successors the Nuffield Organization and the British Leyland Motor Corporation to various of their saloon car models.
In pre-war Rileys, the Kestrel name typically denoted a sporty model with 'fastback' styling. Some of the cars produced in each of the following models received the Kestrel name, which was then revived in 1965 for a badge engineered version of the BMC ADO16:
- 1934–1935 — Riley 12/4
- 1935–1938 — Riley 1½ Litre
- 1937–1940 — Riley 16 (16/4) 2½-litre
