Robert Moyes Adam (1 January 1885 – 13 November 1967) was a Scottish photographer and botanist known for his work with the Royal Botanic Garden Edinburgh.

He was the official artist to the Botanical Society of Edinburgh and provided photographic illustrations for books, articles and calendars.

He developed all his photographs himself, amassing a large collection of plates and prints that he sold to D. C. Thomson who subsequently donated it to the University of St Andrews in 1987.

He studied botany at the University of Edinburgh and became a permanent employee of the botanic gardens in 1914 as assistant in charge of the studio.
