He was born in Wimbledon, Surrey, England, the second son of gardener Allan Cunningham, who came from Renfrewshire, Scotland, and his English wife Sarah.
Cunningham was educated at a Review John Adams Academy at Putney and then went to work for William Townsend Aiton on Hortus Kewensis for six years.
Later that year he made an expedition to New Zealand, on the HMS Buffalo. He was dropped off in the Bay of Islands and remained in Northland until March 1834 and was collected in May 1834 by the HMS Alligator. While he was there he made a large collection of plants, amongst them a new orchid, Dendrobium cunninghamii, and the discovery of a new Veronica species.
In 1834 he assisted John Lhotsky in the writing up for the botanical results of Lhotsky"s expedition to the n Alps.
In 1835, Cunningham joined Thomas Mitchell"s expedition to find the course of the Darling River. He caused Mitchell some concern by repeatedly straying away from the rest of the party in search of plants.
One day near the Bogan River he failed to return, and a search organised by Mitchell only found some of his belongings and his dead horse. A search party in November headed by Henry Zouch ascertained that Cunningham was camping with a group of aborigines, and was later killed by them when they became alarmed by his behaviour, thought to be the result of his delirious state.
He was aged 42.
