Healesville is a town in Victoria, Australia, 64 km north-east from Melbourne's central business district, located within the Shire of Yarra Ranges local government area. Healesville recorded a population of 7,589 in the 2021 census.

Healesville is situated on the Watts River, a tributary of the Yarra River.

The outskirts of Healesville is home to a wildlife sanctuary, called Healesville Sanctuary.

Traffic to the more distant Gippsland and Yarra Valley goldfields in the 1860s resulted in a settlement forming on the Watts River and its survey as a town in 1864. It was named after Richard Heales, the Premier of Victoria from 1860–1861. The post office opened on 1 May 1865. The town became a setting off point for the Woods Point Goldfield with the construction of the Yarra Track in the 1870s.

Healesville is known for the Healesville Sanctuary, a nature park with hundreds of native Australian animals displayed in a semi-open natural setting and an active platypus breeding program.

The Yarra Valley Railway operates from Healesville Station on every Sunday, most public holidays and Wednesday to Sunday during school holidays.

Schools in Healesville include the Healesville Primary School, St Brigid's Catholic primary school, the rural Chum Creek Primary School, Badger Creek Primary School, Healesville High School and Worawa Aboriginal College, an Aboriginal school whose former students include noted Australian Rules Footballer David Wirrpanda.

Much of what is now Healesville lies on the ancestral land of the Wurundjeri people. An Aboriginal reserve known as Coranderrk, set up in 1863, was located just south of the main township.

Industries in and around Healesville include sawmilling, horticulture, tourism and viticulture.

Healesville has an active CFA (Country Fire Authority) volunteer fire brigade established in 1894. The Healesville Rural Fire Brigade was formed in 1941, then disbanded and membership amalgamated with the Healesville Urban Fire Brigade in 1985. The amalgamation of the Chum Creek Rural Fire Brigade with the Healesville brigade occurred in 1996. The Healesville Fire Brigade now operates a main and a satellite station with members from both the Healesville and Chum Creek areas.

Healesville has been a tourist destination since the 1880s, with the Grand Hotel built in 1888, and the 60-room Gracedale House in 1889 is the best in the area.

A Tourist and Progress Association was created in the 1920s. The association published "Healesville, The World-famed Tourist Resort", listing over 40 beauty spots and 20 hotels and guest houses.

The construction of the Maroondah Dam in the 1920s brought several hundred workmen to Healesville. Their departure and the onset of the 1930s depression exposed Healesville's restricted range of industries. Timber and tourism were not stable enough for sustained and reliable growth. Notwithstanding the depression, the 1930s saw increased motor tourism (partly bypassing Healesville) and decreased railway patronage. Only 10% came by rail at Easter 1934. Tourism was still active but a local newspaper commented that Healesville would be "heaps better off calling itself the good-time town instead of the world-famed-tourist-resort—that's got whiskers on it".

In modern times Healesville has become a major centre for tourism based around the wine and food industries of the Yarra Valley, with attractions including Healesville Sanctuary, Badger Weir Picnic Area, Yarra Valley Railway, Healesville Organic Market, numerous cafes and restaurants, and volunteer-run events such as the Healesville Music Festival, Open Studios, and the Yarra Valley Rodeo.

The Memo, a centre for community arts and cultural activities, was built in 1924 as a soldier's memorial hall.

The Internet Movie Database has Healesville and its environs as the filming locations for a number of films and TV programs: the Australian TV series Young Ramsay (1977), Felicity (1979), the natural history TV series Life on Earth (1979), Frog Dreaming (1986), the Australian TV short film Harry's War (1999) and Killer Elite (2011).
