Mundubbera (/mʌnˈdʌbərə/ mun-DUB-ər-ə) is a rural town and a locality in the North Burnett Region, Queensland, Australia. In the 2021 census, the locality of Mundubbera had a population of 1,120 people.

Mundubbera is the self-proclaimed "Citrus Capital of Queensland", although this is disputed by the neighbouring (and rival) town of Gayndah.

The town is in the Wide Bay–Burnett region on the Burnett Highway, 363 kilometres (226 mi) north west of the state capital, Brisbane, 209 kilometres (130 mi) north of Dalby and 200 kilometres (120 mi) west of the regional centre, Bundaberg. The Mundubbera-Durong Road exits to the south.

Mundubbera is built on the bank on the Burnett River.

The Mundubbera district is bounded on the east by the Binjour Plateau and on the south and west by the Burnett River. Devonian, Carboniferous, Triassic, and post-Triassic sediments have all been found in the district. Devonian and Carboniferous sediments are incorporated into the late or post-Permian folds which affect the Yarrol Basin. A large syncline is exposed, commonly called the Mundubbera Syncline. Folded Triassic strata are found in the western part of the district in a fault block. There is evidence of Tertiary or post-Triassic sediments in horizontal sandstone. Near Riverleigh, fossil corals were found in limestone during the 1920s. These were studied by Dorothy Hill of the University of Queensland.

Gureng Gureng (also known as Gooreng Gooreng, Goreng Goreng, Goeng, Gurang, Goorang Goorang, Korenggoreng) is an Australian Aboriginal language spoken by the Gureng Gureng people. The Gooreng Gooreng language region includes the towns of Bundaberg, Gin Gin and Miriam Vale extending south towards Childers, inland to Monto and Mt Perry. Wakka Wakka (Waka Waka, Wocca Wocca, Wakawaka) is an Australian Aboriginal language spoken in the Burnett River catchment. The Wakka Wakka language region includes the landscape within the local government boundaries of the North and South Burnett Regional Council, particularly the towns of Mundubbera, Cherbourg, Murgon, Kingaroy, Gayndah, and Eidsvold.

The name of the town comes from the name of a pastoral property established in 1848 by H.P. Bouverie. It is believed to be an Aboriginal word, possibly from the Kabi language, meaning sharp ridges or climbing steps cut in a tree. It has also been suggested it may mean meeting place of the waters referring to the confluence of the Burnett, Auburn and Boyne rivers just upstream from Mundubbera.

European settlement took place in the late 1840s. A town reserve was established on 26 November 1861. Closer settlement, involving migrants from Germany, Britain and the Netherlands, did not take place until the early 1900s and the town was established in its existing site prior to World War I.

Mundubbera Post Office opened by 1 July 1912 (a receiving office had been open from 1911).

Mundubbera State School opened on 7 November 1913. The school was originally on land bordered by Stuart-Russell, Mahoney and Leichhardt Streets. In 1963, a new site in Bunce Street was developed to offer secondary schooling to Year 10. New classrooms for primary schooling were added in Bunce Street in 1980.

The Mungar Junction to Monto railway line serviced the town from 1914.

A library was established in Mundubbera in December 1933 in the School of Arts.

The Mundubbera War Memorial commemorating those from the district who served in World War I was unveiled by the Member of the Queensland Legislative Assembly for Brisbane and Minister for Works, Mick Kirwan, on 27 May 1928.

Henry Zipf planted the first citrus orchards in 1933 and established Mundubbera as a major producer of export citrus. The recent (2006) drought and the aftereffects of the 2004 Citrus canker outbreak in Emerald has had a dampening effect of the citrus industry in the area.

The Mundubbera Vietnam Veterans Memorial commemorates those who served in the Vietnam War. It is located beside the RSL Memorial Hall.

On 11 November 1995, members of the RSL planted a Lone Pine war memorial tree from a seedling whose lineage links back to Gallipoli.

Mundubbera has a number of heritage-listed sites, including:

• Mundubbera Butter Factory (also known as Maryborough Co-operative Dairy Association Butter Factory), 26 Bowen Road
• Mundubbera Cemetery, Kinchela Street
• O'Regan Memorial Gates, Leichhardt Street
• former Mundubbera Shire Hall and Bloxsome Memorial Building (also known as Mundubbera Library), Lyons Street
• Mundubbera War Memorial, intersection of Lyons and Bouverie Streets
• Jones Weir, Seligmann Avenue

The economy Mundubbera is predominantly agriculture and forestry. The major agricultural activities in Mundubbera are cattle grazing and, in the irrigated areas, fruit growing. Fruit grown in the Mundubbera area includes citrus, mangoes, avocadoes and stone fruit. In addition, Mundubbera is Queensland's largest producer of table grapes.

During the fruit picking seasons Mundubbera can double in size as many itinerant workers and backpackers from around the world come to the town looking for work on the orchards. Seasonal workers are accommodated in two large caravan parks in Mundubbera itself or in many on-site parks. Since 2010, workers from Tonga and Papua New Guinea have been supported through the Pacific Seasonal Worker Pilot Scheme. The success of this endeavour has meant that the Seasonal Worker Program will be fully operational from 1 July 2012.

Supporting the fruit industry are businesses such as a fruit juice processor and several packing sheds. Bugs for Bugs, an integrated pest management business, raises insects in the old butter factory. These insects that act as a biological control for common fruit pests, reducing chemical insecticide use.

With large areas of State forest in the shire, Mundubbera also has a large timber industry with a mill in Mundubbera town. Other industries include piggeries and dairying. Commercial activity is limited and consists mainly of small businesses supporting local residents and farmers. The town has two hotels, two motels and an IGA supermarket, plus the usual small-town services such as a butcher, baker, newsagency, post office and a public library open to the general public.

The town is about 1 kilometre (0.62 mi) south of the intersection of the Burnett Highway and the Mundubbera–Durong Road. The Burnett Highway links Mundubbera with Gayndah and Goomeri to the east; and Eidsvold, Monto and Biloela to the north. The Mundubbera-Durong links Mundubbera to Dalby and Toowoomba in the Darling Downs. This road is single lane bitumen in places. Public transport is limited. In 2005 the only public transport servicing Mundubbera was a bus service operating once a week on Thursdays to Bundaberg and on Wednesdays and Fridays to Maryborough. By 2022, the bus service to Bundaberg was thrice weekly and to Maryborough was once weekly.

In 2012 the Queensland Government under the Premiership of Campbell Newman announced that the railway line would no longer be looked after.

Mundubbera is host to a limited range of primary and secondary school facilities. Primary schools in the area include the small school cluster of the rural schools of Boynewood SS (opened 1915), Binjour Plateau SS (1913), Monogorilby SS (1936) and Riverleigh SS (1914); Riversleigh SS was closed at the end of 2009 due to lack of enrolment.

While Mundubbera attracts seasonal workers from around the world, tourism remains relatively undeveloped.

Some attractions include:

• The nearby Auburn River National Park is a good location to find Queensland Lungfish (Neoceratodus forsteri), known locally as Ceratodus, a rare living fossil found only in the Burnett and Mary Rivers. This park is popular with bush walkers and rock climbers. It features cascades, great swimming spots, caves, balancing rocks and superb scenery.
• The town lookout on the entrance to town on the Burnett Highway is home to a Black stump, to symbolise Mundubbera's location on the edge of the Outback.
