Macleay was born on Ross-shire, Scotland, eldest son of William Macleay, provost of Wick. Alexander had a classical education, before relocating to London and becoming a wine merchant with his business partner William Sharp - after whom his first son was named. In 1795 he was elected a fellow of the Linnean Society of London, also serving as its Secretary, and was also appointed chief clerk in the prisoners of war office. When the office was linked with the Transport Board after war broke out, Macleay became head of the correspondence department and by 1806 secretary. The Board was abolished in 1815, and Macleay retired on an annual pension, of £750.
Macleay's chief natural history interest was entomology, principally lepidoptery, and he possessed the finest and most extensive collection then existing of any private individual in England and possibly the world. This included the British Collection of John Curtis now housed in Melbourne, Australia. In 1813, he was elected a foreign member of the Royal Swedish Academy of Sciences.
Macleay is remembered in the history of biology for his proposal of the quinarian system. This was an attempt to classify animals into related groups and was put forward in Part 2 of his book "Horae Entomologicae" (1821). According to his reasoning each major group of animals could be subdivided into 5 subgroups, and each sub-group could be further divided into 5. Major groups could also be related to other groups or subgroups by overlaps known as osculations. These proposals were taken very seriously at the time, and Charles Darwin, who got to know Macleay after he returned from the Beagle voyage, tried to fit these ideas into his evolutionary schemes up to about 1845 (see "The Development of Darwin's Theory" by Dov Ospovat, 1981). The ideas were also taken up by William Swainson.
On 14 June 1825, Macleay was appointed Colonial Secretary for New South Wales. He arrived in Sydney in January 1826, with his wife Eliza, 9 of his 10 surviving children, and his extensive collection. He was soon working twelve hour days and on 17 July 1825 was nominated to the New South Wales Legislative and Executive Councils, holding both positions until December 1836. Macleay represented Counties of Gloucester, Macquarie, and Stanley in the partially elected Legislative Council from June 1843 until 19 June 1848, a month before his death. Originally residing at the Colonial Secretary's House in Macquarie Place, Macleay was granted land at Elizabeth Bay by Governor Ralph Darling, where he constructed Elizabeth Bay House and laid out an extensive botanic garden.
Macleay was also very active beyond his scientific pursuits and was the foundation president of the Australian Club.
Macleay married a Miss Barclay of Urie. He was the father of the entomologist William Sharp Macleay who expanded his father's collection and of George Macleay, also a zoologist. Sir William John Macleay was his nephew.
