Lilydale is a town and outer suburb of Melbourne, Victoria, Australia, 34 km north-east from Melbourne's central business district, located within the Shire of Yarra Ranges local government area. Lilydale recorded a population of 17,348 at the 2021 census. 
Situated in the Yarra Valley, it began as a town within the former Shire of Lillydale and is also notable as the burial site of Dame Nellie Melba (Lilydale Cemetery).
It is both a residential area of metropolitan Melbourne and an industrial area on the city's rural-urban fringe.
Some prefer to believe the town was named after an 1852 song "Lilly Dale" by H. S. Thompson but evidence shows it was named after an early settler, Lilly de Castella. Most of Victoria has been named after prominent citizens or with traditional Aboriginal names.  Lilly de Castella was one of four daughters of Lieutenant-Colonel Joseph Anderson and his wife Mary. Joseph Anderson was one of eight nominated (non-elected) members of the Victorian Legislative Assembly. Lilly was born Elizabeth Anne on Norfolk Island, where her father was commandant from 1835 to 1839. Lilly was a typical Victorian pet-name for girls named Elizabeth. The family settled in South Yarra in 1848 and were friends of Lieutenant-Governor Charles La Trobe and his wife Sophie. Mary Anderson was a pioneer member of the Melbourne Mechanics Institute. Colonel Anderson was also a close friend of Crown Surveyor Clement Hodgkinson and was a pallbearer at the funeral of Governor Sir Charles Hotham, who died on 31 December 1855. Lilly married Paul de Castella in 1856; Lieutenant-Colonel Anderson co-owned the couple's Yering Station. Anderson Street in Lilydale was named after the Colonel, and the parallel Castella Street was named after his son-in-law, Lilly's husband Paul.
