Cosmo Nelson Innes FRSE (9 September 1798 – 31 July 1874) was a Scottish advocate, judge, historian and antiquary.

[3] He then undertook further studies at the universities of Aberdeen and Glasgow, and at Balliol College, Oxford (1817–1820)[4] graduating with a BA 1820.

He was admitted to the Faculty of Advocates in 1822, and was appointed Professor of Constitutional Law and History at the University of Edinburgh in 1846.

[6] From 1840 to 1852 he was Sheriff of Moray during which time he had to deal with protesters angry at the continued export of grain from their district after the potato crop on which they relied heavily was lost to blight.

On Wednesday 27 January 1847, Innes and his special constables were repulsed by a mob after they attempted to arrest the leaders of the protesters who had unloaded oatmeal from the cargo vessel James and Bessie in Burghead harbour and returned it to the grain-merchant's granary.

[10] The grave lies on the east side of the main west path, just beyond the large Celtic cross to Horatio McCulloch.

Photographic works include "A Tour: The Coast of Spain" (an album of 1857); Midcalder Church (1856); Dunrobin Castle (1856); and Elgin Cathedral (1856).

[1] From 1836 he and his wife were appointed the formal guardian of their niece, Isabella Grant, whose parents had died in India.
