Maroochydore (/məˈruːtʃidɔːr/ mə-ROO-chee-dor) is a coastal town in the Sunshine Coast Region, Queensland, Australia. In the 2021 census, the urban area of Maroochydore had a population of 63,673 people.

The city was subdivided from the Cotton Tree reserve by Surveyor Thomas O'Connor in 1903. The land was acquired from William Pettigrew who had a timber depot at what is now Wharf Street. Its name comes from the Yuggera language word Muru-kutchi, meaning red-bill and referring to the black swan, which is commonly seen in the area.

Maroochydore is a major commercial area of the Sunshine Coast with most shopping precincts located in the central business district. It is home to the Sunshine Plaza shopping centre and the Sunshine Coast's major bus interchange for Translink services operated by Kinetic Group. Maroochydore is also a venue of major surf sport carnivals, and is a popular holiday point from which to travel the rest of Queensland.

The boundaries of the Maroochydore as a locality are well-defined. As a town, Maroochydore does not have strict boundaries. The central business district (CBD) for the area is located on Horton Parade, Maroochydore.

Maroochy Waters is a waterfront, residential estate located in Maroochydore adjacent to the Maroochy River in Queensland, Australia. It is one of the last canal projects to be built in Queensland with direct access to the river system and the Coral Sea. Sunshine Coast Region Council has an annual dredging program to replenish the sand beaches. The canals plus all infrastructure were built in three stages in the late 1970s, mid 1980s, and the early 1990s. The deep water canal plays a role in flood relief and the land is higher than Maroochydore CBD which has recorded floods in the last 30 years. The canal's main reach, which extends for more than one km, was the training ground for 1992 Olympic K–1 1000 m gold medalist Clint Robinson.

Maroochydore Post Office opened on 4 October 1922 (a receiving office had been open from 1891 until 1898, and from 1916).

Our Lady Star of the Sea (Stella Maris) Catholic Church was officially opened by Archbishop James Duhig on Sunday 15 October 1950. It replaced an earlier church which had become inadequate for the growing congregation. The 1950 church could seat 170 people in the nave and a further 150 people on the verandahs on either side of the church. Timber from the recently demolished St Joseph's Catholic Church in Nambour was used to construct the Maroochydore church to reduce the costs. The architect was Frank Cullen and the contractor was K. D. Morris.

The Maroochydore Library opened in 1975.

Horton Park Golf Club is in Maroochydore. The club relocated to Bli Bli in May 2015 and changed names to Maroochy River Golf Club.

The relocation of the golf course allowed the Sunshine Regional Council to develop the old golf course into a new city centre for the region known as Sunshine Central.

The redevelopment is next to Sunshine Cove, a new sustainable residential and commercial development that has revitalized the general town centre and the development won the award from the Urban Development Institute of Australia for the best residential property Development at its annual Australian awards night in 2016.
