Allan Cunningham (13 July 1791 – 27 June 1839) was an English botanist and explorer, primarily known for his travels in Australia to collect plants.
Cunningham was born in Wimbledon, Surrey, the son of Allan Cunningham (head gardener at Wimbledon Park House), who came from Renfrewshire, Scotland, and his English wife Sarah (née Juson/Jewson née Dicken). Allan Cunningham was educated at a Putney private school, Reverend John Adams Academy and then went into a solicitor's office (a Lincoln's Inn Conveyancer). He afterwards obtained a position with William Townsend Aiton superintendent of Kew Gardens, and this brought him in touch with Robert Brown and Sir Joseph Banks.
On Banks' recommendation, Cunningham went to Brazil with James Bowie between 1814 and 1816 collecting specimens for Kew Gardens. On 28 September 1816 he sailed for Sydney where he arrived on 20 December 1816. He established himself at Parramatta. Among other explorations, he joined John Oxley's 1817 expedition beyond the Blue Mountains to the Lachlan and Macquarie rivers and shared in the privations of the 1,200 miles (1,930 km) journey. He was able to collect specimens of about 450 species and gained valuable experience as an explorer.
